I guess we need to redo the start with the correct reading of Orvar.
Unless we find a way to get an extra layer for combat as well, Hoarding Ogre + Moraug, Fury of Akoum simply add two activations of layer 7 for two card slots, breaking even. I guess it's easier to just not bother with them.
Turn 2:
Play Forest.
Cast For the Family targeting Goldhound. Leave it on the stack.
Tap the remaining land and sacrifice the Goldhound to cast Tibalt's Trickery, targeting the For the Family. Counter it, mill 3 cards, then exile and cast Wizard's Spellbook. (3 cards in hand)
5th Exile: Lorehold Command. Fetch Sea Gate Stormcaller. Untap the Spellbook. Command gives all creatures indestructible and haste, and we sacrifice a land to draw 2 (6 cards in hand). Resolve Tibalt's Trickery to cast Orvar, the All-Form. Keep it on the stack.
Tap 5 of the creatures for 5 green mana. Exile Spara's Adjudicators from hand and let Sea Gate Stormcaller tap for blue (GGGU, 5 cards in hand)
Cast Double Major targeting the Orvar spell, get a SGS copy, resolve all of them. (3 Orvars, GG, 4 cards in hand)
Resolve down to the first trickery and tap Orvar for G (5 Orvars, GGG, 4 cards in hand)
Cast For the Family twice, targeting Orvar (17 Orvars, G, 2 cards in hand)
Resolve Tibalt's Trickery, mill 1 and cast Bloody Betrayal, targeting Sea Gate Stormcaller. Get 17 token copies. Untap it and tap for U
Resolve Tibalt's Trickery, mill 1 and cast Jin-Gitaxias, Progress Tyrant. In response cast Double Major and get 17 SGS copies. Let everything resolve to end up with 19 Jins. (1 card in hand)
Resolve down to the Tibalt's Trickeries, tapping creatures for 19 more mana and going up to 49 Orvars. Use all that mana on For the Family: Aberrant Mind Sorcerer, 17x Orvar, Jin. This gets us to 3*2^21+1=6291457 Orvars and as many fresh Jins.
Then we cast Bloody Betrayal of Tibalt's Trickery to get more mana and do it again: more than 2^6291479 Orvars and fresh Jins.
We have another Tibalt's Trickery to go to more than 2^2^6291479 Orvars, Jins and Xorns.
Resolve Turntimber Symbiosis to fetch Scaled Herbalist, resolve Lorehold Command to give it haste and put the Snow-Covered Swamp into play. Use the black mana to cast Thieves' Tools and get some some Jin copies, each of which creates a few treasure tokens.
I have not tried getting Jin-Gitaxias earlier, since we'd then need Bury in Books to cast it again before we can create non-legendary copies. But that could be something to explore for improvements.
I meant we need 2 Rowan, Scholar of Sparks emblems. So even a single cast of Confront the Past would be enough, afterwards it can be exiled. Though it could also be used to get planeswalkers without paying expensive colors for the start, so we can have the emblems ready before casting Thieves' Tools.
What would be the problem with fetching Rowan? getting extra emblems from the -4 wouldn't hurt anything. And the -1 deals damage to the opponent. We can't deal excess damage to them without ending the game, so this can never trigger Toralf, God of Fury. And it is limited by the opponents life anyway.
Getting Will, Scholar of Frost to draw cards could be bad. But we don't have a cheap way to get that one back into the graveyard. And as it is the back-side of the card I don't think we can get him with Confront the Past anyway.
We need to keep the following 8 instants/sorceries:
Behold the Mutiverse
Bury in Books
Mammoth Growth
Plummet
Roiling Regrowth
Thraben Exorcism
Tibalt's Trickery
Markov Retribution
so we can exile the remaining 15 instants/sorceries:
Double Major
FIrst Day of Class
Valakut Awakening
When We Were Young
Confront the Past
Shatterskull Smashing
4x For the Family
Lorehold Command
Tibalt's Trickery
3x Bloody Betrayal
so, combined with Lithoform Engine, we get 16 activations of Layer 7, for 10 -> 10 -> 10 -> 10 -> 10 -> 17 -> 8 damage.
Oh, casting Lithoform Engine for the first time has the same power as exiling an instant/sorcery. So we reach 10 -> 10 -> 10 -> 10 -> 10 -> 18 -> 8.
Edit: Ah, I didn't notice that your previous list had 61 cards, so 10 -> 10 -> 10 -> 10 -> 10 -> 17 -> 8 should be correct.
I used 2 copies of Double Major for the start, so another one should be among the "exilable spells". Though apart from the spells used during the start the composition of those doesn't really matter. I think there is still enough room to have one of them be Culmination of Studies for that little bit of extra value we get from exiling the Snow-Covered Swamp.
Edit: Weigh Down is an exilable spell that gives us some miniscule improvement by turning superfluous creature cards into green mana, which is worth slightly more than the black it costs
Turn 2:
Play Forest.
Cast For the Family targeting Goldhound. Leave it on the stack.
Tap the remaining land and sacrifice the Goldhound to cast Tibalt's Trickery, targeting the For the Family. Counter it, mill 3 cards, then exile and cast Wizard's Spellbook. (3 cards in hand)
5th Exile: Lorehold Command. Fetch Sea Gate Stormcaller. Untap the Spellbook. Command gives all creatures indestructible and haste, and we sacrifice a land to draw 2 (6 cards in hand). Resolve Tibalt's Trickery to mill 1 and cast Orvar, the All-Form. Keep it on the stack.
Tap 5 of the creatures for 5 green mana. Exile Spara's Adjudicators from hand and let Xorn tap for blue (GGGU, 5 cards in hand)
Cast Double Major targeting the Orvar spell, get a SGS copy, resolve all of them. (3 Orvars, GG, 4 cards in hand)
Cast For the Family twice, targeting Orvar (9 Orvars, 2 cards in hand)
6th Exile: Bloody Betrayal. Build stack to look like this:
-----------
8x Orvar token creation
9x Aberrant Mind Sorcerer token creation
Bloody Betrayal (targeting Aberrant Mind Sorcerer)
Lorehold Command (targeting Orvar + indestructible, haste)
Invoke the Winds (targeting Wizard's Spellbook)
Turntimber Symbiosis
Tibalt's Trickery (targeting Turntimber Symbiosis)
Turntimber Symbiosis
-----------
Resolve down until the spellbook untaps. Tap Orvar and the Mind Sorcerer for GG, get instants and sorceries back (9 Orvars, GG, 2 cards in hand + 9ish instants/sorceries)
Cast For the Family 2 times, targeting Orvar and then Xorn (17 Orvars, 18 Xorns)
Resolve Turntimber Symbiosis to fetch Jin-Gitaxias, Progress Tyrant.
Resolve Tibalt's Trickery, mill 1 and cast Thieves' Tools. Get a Jin copy and let the copy resolve. Get 19 treasures.
In response to the original Thieves' Tools we can use those 19 treasures to increase the Xorn count. Doing the simple thing and doubling Orvars 17 times we get to more than 2^21 Xorns. We are missing the Arlinn, the Pack's Hope emblem, so we can't really get the G stage going, but we can probably do better than doubling.
Resolve the Thieves' Tools to get more than 2^21 treasures. Certainly enough to get access to the entire combo quickly and then go through it.
Let me see if I have the basics of the stages:
G/b
G for Mammoth growth copies animated swamp which casts skyclave shade to tap for G
G for plummet kills skyclave shade, but can not target swamp
Both spells can make more copies of our useful creatures (and we need mammoth growth as a spell that doesn't get copied by stormcaller? isn't Jin gitaxias +rowan emblem enough spell copying?)
W stage
W for exorcism makes copies of enchantments, path to the world tree fetches the plains, herbalist puts it in play, sac it to harrow, and the saga puts it back in the library.
Am I missing something? how does this not go infinite?
tap plains, sac it to harrow, use G stage to make fresh Jins and other creatures, cast exorcism, make a boseju, then a path to the world tree, get the plains back in hand herbalist it in and profit a bunch of exorcisms on the stack.
U stage
Secluded courtyard and Sparra's adjudicators work beautifully together.
U puts the citizen that makes a U on top
U draws the citizen and the nonbasic land
Though what is Brightclimb pathway for? we already have enough other lands it seems.
Toralf stage
Cabaretti charm kicks off a standard Toralf+lifelink stage
Slaughter specialist ensures the opponent has enough 1/1s
Novice occultist turns life into cards
A cast of Thraban Exorcism can target one enchantment, to target another you need to cast it again.
I think a cheaper version of Mammoth Growth is fine, we can probably switch for one I guess.
As for Brightclimb Pathway... hmmm, yeah. Why don't we just use the Plains instead?
Edit: I suppose one white mana is not enough, since we need to cast Thraban Exorcism to get it. So the Brightclimb Pathway is for the second white mana to profit each cycle.
Iijil pointed out that Sea Gate Stormcaller adds a layer with Tibalt's Trickery. We start by putting a lot of spells (e.g. Plummet) on the stack. Then we spend a red mana to cast Tibalt's Trickery targeting a Plummet copy, get a bunch of triggers from kicked Sea Gate Stormcallers, and counter it. For each SGS or Jin-Gitaxias trigger, we use a Tibalt's Trickery to counter a Plummet copy, and cast Tibalt's Trickery again, getting SGS triggers again. For each of these SGS triggers, we use the first Tibalt's Trickery to counter the second, and cast Meeting of the Five.
I think we can! But, I don't know if we can implement the combo with just one copy of Choose Your Weapon, without having to add something somewhere else.
Ah yeah we don't have Aberrant Mind Sorcerer etbs quite cheap enough, so the Archery mode can't be responded to with the 2 handed mode. Maybe Vanquish the Weak? It cant target the animated swamp or the skyclave shade due to Arlinn's +1/+1 counter, and we can play the sorcerer, orvar, and mage's attendant before Arlinn makes things too big. Not as good as an extra card but should still be a minor improvement.
Edit: nevermind it looks like we go infinite comboing at sorcery speed without Arlinn's +
Oh, interesting. Could Vanquish the Weak make Confront the Past unnecessary? If so we could still save a card... I don't really know at this point though.
I don't think Vanquish the Weak can go infinite. It can target and destroy Skyclave Shade if we don't use flash for creatures, but that in itself doesn't do anything. Skyclave Shade only gets dangerous once it taps for green, and to do that we need to resolve the trigger it gets from First day of Class. The moment it gets haste it also gets +1/+1 and gets out of reach for Vanquish the Weak.
And I think that can be achieved with Croaking Counterpart. That + Double Major can produce a non-legendary 1/1 Frog-Gitaxias in the start and later get exiled. So we can get to 10 -> 10 -> 10 -> 10 -> 10 -> 18 -> 9.
I don't think it is possible to get a 1/1 Snow-Covered Swamp with Croaking Counterpart and Avalanche Caller. Since the Swamp copies wouldn't be creatures until we animate them individually. But if I missed something and it is possible to get a swamp that we can target with Vanquish the Weak, then that goes infinite.
With Vanquish the Weak we should be able to cut the Forest. It was needed to generate green mana at the top of W stage. But black mana is basically free there, and with Vanquish the Weak that extends to reusing instants and generating copies of instants. So we only need 1 green to cast Roiling Regrowth and we can generate 2 green with landfall triggers from our 2 basics:
Start with a Path to the World Tree layer on the stack, Snow-Covered Swamp and Plains in hand, Skyclave Shade in the graveyard:
1. put the swamp into play. Resolve the landfall trigger and cast Skyclave Shade. Tap it for G.
2. use G to cast Roiling Regrowth getting a bunch of copies. Resolve a copy to sacrifice Skyclave Shade.
3. put the plains into play. Resolve the landfall trigger and cast Skyclave Shade. Tap them for WG.
4. resolve more Roiling Regrowth copies to sacrifice Skyclave Shade and both basics.
5. use W to cast Thraben Exorcism on Boseiju Reaches Skyward. That gets both basics into the library.
(6.) resolve 2 trigger form the layer on the stack to get the basics back to hand.
So we generate G for every two Orvar triggers on Path to the World Tree. Enough to accumulate X green before putting a big G stage on the stack.
We now need the Snow-Covered Swamp throughout the combo, so we can't exile it to Culmination of Studies anymore. But playing an extra exilable instant/sorcery instead of the Forest is way better.
The start uses forest but we don't actually need the forest for it, we can announce for the family targeting goldhound, then sac goldhound to pay for it. (or start with blessed defiance as our lifelink source.)
In that start we haven't milled enough for all of those mind sorcerer triggers to be useful, with max milling we hit 8 spells in yard.
Also I think the math missed an orvar doubling in the middle.
Turn 2:
Play Plains.
Cast Blessed Defiance targeting Goldhound. Leave it on the stack.
Tap the remaining land and sacrifice the Goldhound to cast Tibalt's Trickery, targeting the Blessed Defiance. Counter it, mill 3 cards, then exile and cast Wizard's Spellbook. (3 cards in hand)
5th Exile: Lorehold Command. Fetch Sea Gate Stormcaller. Untap the Spellbook. Command gives all creatures indestructible and haste, and we sacrifice a land to draw 2 (6 cards in hand). Resolve Tibalt's Trickery to mill 3 spells and cast Orvar, the All-Form. Keep it on the stack. Yard: bloody betrayal, blessed defiance, shatterskull smashing, and 3 spells
Tap the 5 non-Xorn creatures for 5 green mana. Exile Spara's Adjudicators from hand and let Xorn tap for blue (GGGU, 5 cards in hand)
Cast Double Major targeting the Orvar spell, get a SGS copy, resolve all of them. (3 Orvars, GG, 4 cards in hand)
Cast For the Family twice, targeting Orvar (9 Orvars, 2 cards in hand, yard:bloody betrayal, blessed defiance, shatterskull smashing, 3 spells, Double major, 2x For the Family)
6th Exile: Bloody Betrayal. Build stack to look like this:
-----------
8x Orvar token creation
9x Aberrant Mind Sorcerer token creation
Bloody Betrayal (targeting Aberrant Mind Sorcerer)
Lorehold Command (targeting Orvar + indestructible, haste)
Invoke the Winds (targeting Wizard's Spellbook)
Turntimber Symbiosis
Tibalt's Trickery (targeting Turntimber Symbiosis)
Turntimber Symbiosis
-----------
Resolve down until the spellbook untaps. Tap Orvar and the Mind Sorcerer for GG, get instants and sorceries back (17 Orvars, GG, 2 cards in hand + 8 instants/sorceries)
Cast For the Family 2 times, targeting Orvar and then Xorn (33 Orvars, 34 Xorns)
Resolve Turntimber Symbiosis to fetch Jin-Gitaxias, Progress Tyrant.
Resolve Tibalt's Trickery, mill 1 and cast Thieves' Tools. Get a Jin copy and let the copy resolve. Get 35 treasures.
In response to the original Thieves' Tools we can use those 35 treasures to increase the Xorn count. Doing the simple thing and doubling Orvars 35 times we get to more than 2^40 Xorns. We are missing the Arlinn, the Pack's Hope emblem, so we can't really get the G stage going, but we can probably do better than doubling.
Resolve the Thieves' Tools to get more than 2^40 treasures. Certainly enough to get access to the entire combo quickly and then go through it.
EDIT: I tried a bit to get Arlinn's flash earlier but can't quite make it work, just a few mana short.
Theres another line that gets Jin right before copying Orvar, but it seems worse.
What we'd like would be to somehow have Jin and orvar on the stack simultaneously for sea gate stormcaller+Double major to make both of them nonlegendary so we can get more copies of our first thieves tools, but it doesn't seem like its possible without exiling another card.
It seems that the priorities would be to make a bunch of black mana to save as many of the treasures as possible. From there probably the best for the combo is to get flash, which needs an empty stack. Then we want a 1/1 nonlegendary Jin, which needs to get bounced with Bury in books, and then cast with our second tibalts trickery, copied with double major and finally 1/1'd with croaking counterpart.
From there we should be able to draw the rest of the library and do the whole combo.
Turn 2:
Play Snow-Covered Swamp.
Announce For the Family targeting Goldhound, sac goldhound to pay for it. Leave it on the stack.
Tap the lands to cast Tibalt's Trickery, targeting the FtF. Counter it, mill 3 cards, then exile and cast Wizard's Spellbook. (3 cards in hand)
5th Exile: Lorehold Command. Fetch Sea Gate Stormcaller. Untap the Spellbook. Command gives all creatures indestructible and haste, and we sacrifice Shatterskull pass to draw 2 (6 cards in hand). Resolve Tibalt's Trickery to mill skyclave shade and 2 spells and cast Orvar, the All-Form. Keep it on the stack. Yard: bloody betrayal, shatterskull smashing, and 4 spells
Tap the 4 non-Xorn creatures for GGGG. Exile Spara's Adjudicators from hand and let Xorn tap for blue (GGU, 5 cards in hand)
Cast Double Major targeting the Orvar spell, get a SGS copy, resolve all of them. (3 Orvars, G, 4 cards in hand)
Cast For the Family, targeting Orvar (5 Orvars, 3 cards in hand, yard:bloody betrayal, shatterskull smashing, 3 spells, Double major, For the Family, skyclave shade)
+Arlinn for flash
6th Exile: Bloody Betrayal. Build stack to look like this:
-----------
4x Orvar token creation
5x Aberrant Mind Sorcerer token creation
Bloody Betrayal (targeting Aberrant Mind Sorcerer)
Lorehold Command (targeting Orvar + indestructible, haste)
Invoke the Winds (targeting Wizard's Spellbook)
Turntimber Symbiosis
Tibalt's Trickery (targeting Turntimber Symbiosis)
Turntimber Symbiosis
-----------
Resolve down until the spellbook untaps. Tap Orvar and the Mind Sorcerer for GG, get instants and sorceries back (9 Orvars, GG, 3 cards in hand + 5 instants/sorceries)
Cast For the Family 2 times, targeting Orvar and then Xorn (17 Orvars, 18 Xorns)
Resolve Turntimber Symbiosis to fetch Jin-Gitaxias, Progress Tyrant.
Resolve Tibalt's Trickery, mill 1 and cast Thieves' Tools. Get a Jin copy and let the copy resolve. Get 19 treasures.
In response to the original Thieves' Tools we can use those 19 treasures to increase the Xorn count. Doing the simple thing and doubling Orvars 19 times we get to more than 2^21 Xorns. We are missing the Arlinn, the Pack's Hope emblem, so we can't really get the G stage going, but we can probably do better than doubling.
Now we have access to nearly the entire green stage so we should be able to do a LOT better than doubling. We do lose some efficiency to the overhead of animating the swamp, getting Sigarda's summons, Mage's Attendant, and first day of class, etc but there should still be enough treasure left to beat the 2^40 number from the above start.
Getting the Arlinn emblem is the only piece of setup we can't do at instant speed (using Tibalt's Trickery when necessary). So I think we can get access to all 4 stages and the layers up to red mana quickly and still have 10 or 11 treasures left with the Thieves' Tools on the stack.
Start by casting For the Family, targeting Sea Gate Stormcaller. Create one token. Cast another FtF targeting SGS. Create two tokens then resolve the SGS ability to put a FtF copy on the stack. Then cast Tibalt's Trickery, getting two copies. Those 3 TTs can target the 3 FtFs on the stack. We spent 4 mana so far.
Resolve the first TT to cast Bury in Books on Jin-Gitaxias, Progress Tyrant. (Tokens are created and one sticks around.) Resolve the second TT to cast Jin. Spend two mana to copy the Jin spell with Double Major. (The spell is copied by Jin and we get 2 tokens.) Spend another mana on FtF targeting the non-legendary Jin to get 17 copies. (Resolve the 2nd Double Major and the original Jin afterwards, so they stay fresh.)
Resolve the 3rd TT to cast a Bloody Betrayal, getting 19 copies from the fresh Jins. This untaps Xorn 20 times to get us 20 WUG mana.
12 treasures are left. We can use the 20 WUG mana to put more counterable spells on the stack before casting the next TT. We need to cast Mage's Attendant to keep the original instants moving while copies are on the stack. It is probably worth it to animate the swamp here and make some progress from that.
I suspect it is possible to get access to everything after cracking only one more treasure for TT. But worst case we need two treasures and still have 10 left.
Edit:
Duh, no Jin-Gitaxias copies we get from targeting it with Bury in Books can stick around without sending the original to the graveyard and fizzling the BiB. So we don't get a copy of Double Major and end up with one less WUG mana.
Unless we find a way to get an extra layer for combat as well, Hoarding Ogre + Moraug, Fury of Akoum simply add two activations of layer 7 for two card slots, breaking even. I guess it's easier to just not bother with them.
Edit: By the way nice improvement!
Edit: Just keeping count, using Double Major with 8 exiles will put our second to last number at 13, while 7 exiles puts it at 14. (I'm assuming Confront the Past eliminates the need for Repository Skaab, but not Abberant Mind Sorcerer.)

Resolve down to the Tibalt's Trickeries, tapping creatures for 19 more mana and going up to 49 Orvars. Use all that mana on For the Family: Aberrant Mind Sorcerer, 17x Orvar, Jin. This gets us to 3*2^21+1=6291457 Orvars and as many fresh Jins.
Then we cast Bloody Betrayal of Tibalt's Trickery to get more mana and do it again: more than 2^6291479 Orvars and fresh Jins.
We have another Tibalt's Trickery to go to more than 2^2^6291479 Orvars, Jins and Xorns.
Resolve Turntimber Symbiosis to fetch Scaled Herbalist, resolve Lorehold Command to give it haste and put the Snow-Covered Swamp into play. Use the black mana to cast Thieves' Tools and get some some Jin copies, each of which creates a few treasure tokens.
I have not tried getting Jin-Gitaxias earlier, since we'd then need Bury in Books to cast it again before we can create non-legendary copies. But that could be something to explore for improvements.

should hopefully deal more than 10 -> 10 -> 10 -> 10 -> 10 -> 15 -> 8 damage.
Edit: Hmm, why do we need at least two of Confront the Past? Or did you mean we just need to cast it twice.
Edit: Hmm, but being able to fetch Rowan seems bad.
Edit: Oh, you can only return it with Rowan face up, and the first ability is harmless.
What would be the problem with fetching Rowan? getting extra emblems from the -4 wouldn't hurt anything. And the -1 deals damage to the opponent. We can't deal excess damage to them without ending the game, so this can never trigger Toralf, God of Fury. And it is limited by the opponents life anyway.
Getting Will, Scholar of Frost to draw cards could be bad. But we don't have a cheap way to get that one back into the graveyard. And as it is the back-side of the card I don't think we can get him with Confront the Past anyway.
Edit:
We don't need Vault Robber anymore, we start with treasures from Thieves' Tools.
Valakut Awakening can be exiled after leaving a copy on the stack. To reuse Thieves' Tools we then spend 2 Lithoform Engines. One to copy Spectral Steel's ability and one to copy Valakut Awakening.
So I think we have 16 exilable spells after the start to reach 10 -> 10 -> 10 -> 10 -> 10 -> 17 -> 8.

We need to keep the following 8 instants/sorceries:
Behold the Mutiverse
Bury in Books
Mammoth Growth
Plummet
Roiling Regrowth
Thraben Exorcism
Tibalt's Trickery
Markov Retribution
so we can exile the remaining 15 instants/sorceries:
Double Major
FIrst Day of Class
Valakut Awakening
When We Were Young
Confront the Past
Shatterskull Smashing
4x For the Family
Lorehold Command
Tibalt's Trickery
3x Bloody Betrayal
so, combined with Lithoform Engine, we get 16 activations of Layer 7, for 10 -> 10 -> 10 -> 10 -> 10 -> 17 -> 8 damage.
Edit: Ah, I didn't notice that your previous list had 61 cards, so 10 -> 10 -> 10 -> 10 -> 10 -> 17 -> 8 should be correct.
I used 2 copies of Double Major for the start, so another one should be among the "exilable spells". Though apart from the spells used during the start the composition of those doesn't really matter. I think there is still enough room to have one of them be Culmination of Studies for that little bit of extra value we get from exiling the Snow-Covered Swamp.
Edit:
Weigh Down is an exilable spell that gives us some miniscule improvement by turning superfluous creature cards into green mana, which is worth slightly more than the black it costs
For a more serious improvement, can we use Rem Karolus, Stalwart Slayer, Unleash the Inferno and Meeting of the Five instead of Markov Retribution to get an additional layer?
Edit2: Err, Cabaretti Charm + Meeting of the Five would be easier and one less card.
Play Shatterskull, the Hammer Pass untapped. (17 life)
Cast Goldhound.
Turn 2:
Play Forest.
Cast For the Family targeting Goldhound. Leave it on the stack.
Tap the remaining land and sacrifice the Goldhound to cast Tibalt's Trickery, targeting the For the Family. Counter it, mill 3 cards, then exile and cast Wizard's Spellbook. (3 cards in hand)
1st Exile: Invoke the Winds. Untap the Spellbook.
2nd Exile: Turntimber Symbiosis. Fetch Aberrant Mind Sorcerer. Get back For the Family. (4 cards in hand) Untap the Spellbook.
3rd Exile: Turntimber Symbiosis. Fetch Ashaya, Soul of the Wild and Xorn. Untap the Spellbook.
4th Exile: Tibalt's Trickery. Fetch Avalanche Caller. Mill 1 and cast Vorinclex, Monstrous Raider. Untap the Spellbook.
5th Exile: Lorehold Command. Fetch Sea Gate Stormcaller. Untap the Spellbook. Command gives all creatures indestructible and haste, and we sacrifice a land to draw 2 (6 cards in hand). Resolve Tibalt's Trickery to mill 1 and cast Orvar, the All-Form. Keep it on the stack.
Tap 5 of the creatures for 5 green mana. Exile Spara's Adjudicators from hand and let Xorn tap for blue (GGGU, 5 cards in hand)
Cast Double Major targeting the Orvar spell, get a SGS copy, resolve all of them. (3 Orvars, GG, 4 cards in hand)
Cast For the Family twice, targeting Orvar (9 Orvars, 2 cards in hand)
6th Exile: Bloody Betrayal. Build stack to look like this:
-----------
8x Orvar token creation
9x Aberrant Mind Sorcerer token creation
Bloody Betrayal (targeting Aberrant Mind Sorcerer)
Lorehold Command (targeting Orvar + indestructible, haste)
Invoke the Winds (targeting Wizard's Spellbook)
Turntimber Symbiosis
Tibalt's Trickery (targeting Turntimber Symbiosis)
Turntimber Symbiosis
-----------
Resolve down until the spellbook untaps. Tap Orvar and the Mind Sorcerer for GG, get instants and sorceries back (9 Orvars, GG, 2 cards in hand + 9ish instants/sorceries)
Cast For the Family 2 times, targeting Orvar and then Xorn (17 Orvars, 18 Xorns)
Resolve Turntimber Symbiosis to fetch Jin-Gitaxias, Progress Tyrant.
Resolve Tibalt's Trickery, mill 1 and cast Thieves' Tools. Get a Jin copy and let the copy resolve. Get 19 treasures.
In response to the original Thieves' Tools we can use those 19 treasures to increase the Xorn count. Doing the simple thing and doubling Orvars 17 times we get to more than 2^21 Xorns. We are missing the Arlinn, the Pack's Hope emblem, so we can't really get the G stage going, but we can probably do better than doubling.
Resolve the Thieves' Tools to get more than 2^21 treasures. Certainly enough to get access to the entire combo quickly and then go through it.

1 Weigh Down
Final daamge: more than 10 -> 10 -> 10 -> 10 -> 10 -> 17 -> 9.
Let me see if I have the basics of the stages:
G/b
G for Mammoth growth copies animated swamp which casts skyclave shade to tap for G
G for plummet kills skyclave shade, but can not target swamp
Both spells can make more copies of our useful creatures (and we need mammoth growth as a spell that doesn't get copied by stormcaller? isn't Jin gitaxias +rowan emblem enough spell copying?)
W stage
W for exorcism makes copies of enchantments, path to the world tree fetches the plains, herbalist puts it in play, sac it to harrow, and the saga puts it back in the library.
Am I missing something? how does this not go infinite?
tap plains, sac it to harrow, use G stage to make fresh Jins and other creatures, cast exorcism, make a boseju, then a path to the world tree, get the plains back in hand herbalist it in and profit a bunch of exorcisms on the stack.
U stage
Secluded courtyard and Sparra's adjudicators work beautifully together.
U puts the citizen that makes a U on top
U draws the citizen and the nonbasic land
Though what is Brightclimb pathway for? we already have enough other lands it seems.
Toralf stage
Cabaretti charm kicks off a standard Toralf+lifelink stage
Slaughter specialist ensures the opponent has enough 1/1s
Novice occultist turns life into cards
I think a cheaper version of Mammoth Growth is fine, we can probably switch for one I guess.
As for Brightclimb Pathway... hmmm, yeah. Why don't we just use the Plains instead?
Edit: I suppose one white mana is not enough, since we need to cast Thraban Exorcism to get it. So the Brightclimb Pathway is for the second white mana to profit each cycle.
Do we need Sea Gate Stormcaller at all then?
Edit: nevermind it looks like we go infinite comboing at sorcery speed without Arlinn's +
Edit: Oh, what's the infinite?
So we can use Vanquish the Weak + Choose your Weapon instead of Plummet + Mammoth Growth, which is a cool idea. By itself it doesn't seem to do anything, except rule out Weigh Down from the exilable spells. But if we could target Jin-Gitaxias, Progress Tyrant with Vanquish the Weak, then we could generate copies of our instants cheap enough and wouldn't need Rowan, Scholar of Sparks anymore.
And I think that can be achieved with Croaking Counterpart. That + Double Major can produce a non-legendary 1/1 Frog-Gitaxias in the start and later get exiled. So we can get to 10 -> 10 -> 10 -> 10 -> 10 -> 18 -> 9.
I don't think it is possible to get a 1/1 Snow-Covered Swamp with Croaking Counterpart and Avalanche Caller. Since the Swamp copies wouldn't be creatures until we animate them individually. But if I missed something and it is possible to get a swamp that we can target with Vanquish the Weak, then that goes infinite.

for 10 -> 10 -> 10 -> 10 -> 10 -> 18 -> 9
Croaking counterpart can't give us a 1/1 swamp so that works.
Start with a Path to the World Tree layer on the stack, Snow-Covered Swamp and Plains in hand, Skyclave Shade in the graveyard:
1. put the swamp into play. Resolve the landfall trigger and cast Skyclave Shade. Tap it for G.
2. use G to cast Roiling Regrowth getting a bunch of copies. Resolve a copy to sacrifice Skyclave Shade.
3. put the plains into play. Resolve the landfall trigger and cast Skyclave Shade. Tap them for WG.
4. resolve more Roiling Regrowth copies to sacrifice Skyclave Shade and both basics.
5. use W to cast Thraben Exorcism on Boseiju Reaches Skyward. That gets both basics into the library.
(6.) resolve 2 trigger form the layer on the stack to get the basics back to hand.
So we generate G for every two Orvar triggers on Path to the World Tree. Enough to accumulate X green before putting a big G stage on the stack.
We now need the Snow-Covered Swamp throughout the combo, so we can't exile it to Culmination of Studies anymore. But playing an extra exilable instant/sorcery instead of the Forest is way better.

Cast Goldhound.
Turn 2:
Play Plains.
Cast Blessed Defiance targeting Goldhound. Leave it on the stack.
Tap the remaining land and sacrifice the Goldhound to cast Tibalt's Trickery, targeting the Blessed Defiance. Counter it, mill 3 cards, then exile and cast Wizard's Spellbook. (3 cards in hand)
1st Exile: Invoke the Winds. Untap the Spellbook.
2nd Exile: Turntimber Symbiosis. Fetch Vorinclex, Monstrous Raider. Untap the Spellbook.
3rd Exile: Turntimber Symbiosis. Fetch Ashaya, Soul of the Wild and Xorn. Untap the Spellbook.
4th Exile: Tibalt's Trickery. Fetch Avalanche Caller. Mill For the Family, Lorehold Command, Bloody betrayal, and cast Aberrant Mind Sorcerer. Get back For the Family. (4 cards in hand) Untap the Spellbook.
5th Exile: Lorehold Command. Fetch Sea Gate Stormcaller. Untap the Spellbook. Command gives all creatures indestructible and haste, and we sacrifice a land to draw 2 (6 cards in hand). Resolve Tibalt's Trickery to mill 3 spells and cast Orvar, the All-Form. Keep it on the stack. Yard: bloody betrayal, blessed defiance, shatterskull smashing, and 3 spells
Tap the 5 non-Xorn creatures for 5 green mana. Exile Spara's Adjudicators from hand and let Xorn tap for blue (GGGU, 5 cards in hand)
Cast Double Major targeting the Orvar spell, get a SGS copy, resolve all of them. (3 Orvars, GG, 4 cards in hand)
Cast For the Family twice, targeting Orvar (9 Orvars, 2 cards in hand, yard:bloody betrayal, blessed defiance, shatterskull smashing, 3 spells, Double major, 2x For the Family)
6th Exile: Bloody Betrayal. Build stack to look like this:
-----------
8x Orvar token creation
9x Aberrant Mind Sorcerer token creation
Bloody Betrayal (targeting Aberrant Mind Sorcerer)
Lorehold Command (targeting Orvar + indestructible, haste)
Invoke the Winds (targeting Wizard's Spellbook)
Turntimber Symbiosis
Tibalt's Trickery (targeting Turntimber Symbiosis)
Turntimber Symbiosis
-----------
Resolve down until the spellbook untaps. Tap Orvar and the Mind Sorcerer for GG, get instants and sorceries back (17 Orvars, GG, 2 cards in hand + 8 instants/sorceries)
Cast For the Family 2 times, targeting Orvar and then Xorn (33 Orvars, 34 Xorns)
Resolve Turntimber Symbiosis to fetch Jin-Gitaxias, Progress Tyrant.
Resolve Tibalt's Trickery, mill 1 and cast Thieves' Tools. Get a Jin copy and let the copy resolve. Get 35 treasures.
In response to the original Thieves' Tools we can use those 35 treasures to increase the Xorn count. Doing the simple thing and doubling Orvars 35 times we get to more than 2^40 Xorns. We are missing the Arlinn, the Pack's Hope emblem, so we can't really get the G stage going, but we can probably do better than doubling.
Resolve the Thieves' Tools to get more than 2^40 treasures. Certainly enough to get access to the entire combo quickly and then go through it.
EDIT: I tried a bit to get Arlinn's flash earlier but can't quite make it work, just a few mana short.
Theres another line that gets Jin right before copying Orvar, but it seems worse.
What we'd like would be to somehow have Jin and orvar on the stack simultaneously for sea gate stormcaller+Double major to make both of them nonlegendary so we can get more copies of our first thieves tools, but it doesn't seem like its possible without exiling another card.
It seems that the priorities would be to make a bunch of black mana to save as many of the treasures as possible. From there probably the best for the combo is to get flash, which needs an empty stack. Then we want a 1/1 nonlegendary Jin, which needs to get bounced with Bury in books, and then cast with our second tibalts trickery, copied with double major and finally 1/1'd with croaking counterpart.
From there we should be able to draw the rest of the library and do the whole combo.
Edit: AHA, yeah early Arlinn is the way to go.
Play Shatterskull, the Hammer Pass untapped. (17 life)
Cast Goldhound.
Turn 2:
Play Snow-Covered Swamp.
Announce For the Family targeting Goldhound, sac goldhound to pay for it. Leave it on the stack.

1st Exile: Invoke the Winds. Untap the Spellbook.
2nd Exile: Turntimber Symbiosis. Fetch Avalanche Caller. Untap the Spellbook.
3rd Exile: Turntimber Symbiosis. Fetch Ashaya, Soul of the Wild and Xorn. Untap the Spellbook.
4th Exile: Tibalt's Trickery. Fetch Aberrant Mind Sorcerer. Get back For the Family. TT Mills Lorehold Command, Bloody betrayal, and another spell and casts Arlinn, the pack's hope. (4 cards in hand) Untap the Spellbook.
5th Exile: Lorehold Command. Fetch Sea Gate Stormcaller. Untap the Spellbook. Command gives all creatures indestructible and haste, and we sacrifice Shatterskull pass to draw 2 (6 cards in hand). Resolve Tibalt's Trickery to mill skyclave shade and 2 spells and cast Orvar, the All-Form. Keep it on the stack. Yard: bloody betrayal, shatterskull smashing, and 4 spells
Tap the 4 non-Xorn creatures for GGGG. Exile Spara's Adjudicators from hand and let Xorn tap for blue (GGU, 5 cards in hand)
Cast Double Major targeting the Orvar spell, get a SGS copy, resolve all of them. (3 Orvars, G, 4 cards in hand)
Cast For the Family, targeting Orvar (5 Orvars, 3 cards in hand, yard:bloody betrayal, shatterskull smashing, 3 spells, Double major, For the Family, skyclave shade)
+Arlinn for flash
6th Exile: Bloody Betrayal. Build stack to look like this:
-----------
4x Orvar token creation
5x Aberrant Mind Sorcerer token creation
Bloody Betrayal (targeting Aberrant Mind Sorcerer)
Lorehold Command (targeting Orvar + indestructible, haste)
Invoke the Winds (targeting Wizard's Spellbook)

Turntimber Symbiosis
-----------
Resolve down until the spellbook untaps. Tap Orvar and the Mind Sorcerer for GG, get instants and sorceries back (9 Orvars, GG, 3 cards in hand + 5 instants/sorceries)
Cast For the Family 2 times, targeting Orvar and then Xorn (17 Orvars, 18 Xorns)
Resolve Turntimber Symbiosis to fetch Jin-Gitaxias, Progress Tyrant.
Resolve Tibalt's Trickery, mill 1 and cast Thieves' Tools. Get a Jin copy and let the copy resolve. Get 19 treasures.
In response to the original Thieves' Tools we can use those 19 treasures to increase the Xorn count. Doing the simple thing and doubling Orvars 19 times we get to more than 2^21 Xorns.
We are missing the Arlinn, the Pack's Hope emblem, so we can't really get the G stage going, but we can probably do better than doubling.
Now we have access to nearly the entire green stage so we should be able to do a LOT better than doubling. We do lose some efficiency to the overhead of animating the swamp, getting Sigarda's summons, Mage's Attendant, and first day of class, etc but there should still be enough treasure left to beat the 2^40 number from the above start.
Getting the Arlinn emblem is the only piece of setup we can't do at instant speed (using Tibalt's Trickery when necessary). So I think we can get access to all 4 stages and the layers up to red mana quickly and still have 10 or 11 treasures left with the Thieves' Tools on the stack.
Start by casting For the Family, targeting Sea Gate Stormcaller. Create one token. Cast another FtF targeting SGS. Create two tokens then resolve the SGS ability to put a FtF copy on the stack. Then cast Tibalt's Trickery, getting two copies. Those 3 TTs can target the 3 FtFs on the stack. We spent 4 mana so far.
Resolve the first TT to cast Bury in Books on Jin-Gitaxias, Progress Tyrant. (Tokens are created and one sticks around.) Resolve the second TT to cast Jin. Spend two mana to copy the Jin spell with Double Major. (The spell is copied by Jin and we get 2 tokens.) Spend another mana on FtF targeting the non-legendary Jin to get 17 copies. (Resolve the 2nd Double Major and the original Jin afterwards, so they stay fresh.)
Resolve the 3rd TT to cast a Bloody Betrayal, getting 19 copies from the fresh Jins. This untaps Xorn 20 times to get us 20 WUG mana.
12 treasures are left. We can use the 20 WUG mana to put more counterable spells on the stack before casting the next TT. We need to cast Mage's Attendant to keep the original instants moving while copies are on the stack. It is probably worth it to animate the swamp here and make some progress from that.
I suspect it is possible to get access to everything after cracking only one more treasure for TT. But worst case we need two treasures and still have 10 left.
Edit:
Duh, no Jin-Gitaxias copies we get from targeting it with Bury in Books can stick around without sending the original to the graveyard and fizzling the BiB. So we don't get a copy of Double Major and end up with one less WUG mana.
