Ugh,
Hmm, what if we give them life and lifelink it back to us? so no planeswalker to get destroyed and fizzle our lifelink. we can use something like aria of flame to give them more life than we need.
Oh and we would need to activate the gideon at sorcery speed, only Gideon Blackblade is indestructable at instant speed, and he goes infinite at sorcery speed.
Kytheon+moonmist is the best I have found. being able to target any creature looks like it goes infinite if it lets us get another Worldfire.
Giving the opponent tokens can just be blown up with EE=0, they have to get the actual card.
Another thought is a planeswalker to take some lifelink damage?
Edit: Stalking Vengeance and a 3 power lifelinker? Abzan kin-guard is a 4 cmc green creature with lifelink. though there are a ton of other options, that was the first alphabetically.
Yarok, the desecrated might be even better and would be able to replace panharmonicon to make up for the planeswalker slot we have to add. (though we would now also need to find a way to get a pw back from Child+Worldfire)
Treacherous Pit-dweller seems ideal, as if we make a token of it with Mimic vat, it doesn't go over to them. (Sleeper agent has a trigger we can respond to with EE=1 to get it on our vat)
Sangromancer can be returned several ways, Though we do have to be careful that we can only make one. I think the least disruptive is to pump it into Smite range with something like Vampire Nocturnus. (we can reveal bloodbond march as much as we want)
Edit: oops, We can still kill the pit dweller with EE=2 to gain 3 life, need higher CMC: Captive Audience?
Hmm, the stack looks tricky there, what we need is a dies trigger for 3 life instead of ETB, Auspicious Ancestor unfortunately also has ivory cup so its no good.
Bartered cow also works via discard so maybe a gravedigger effect would work? (can discard to Phantatog) Edit: Dutiful Attendant or even Iname, life aspect +making everything a spirit
Another option is Sangromancer and some way to force them to either discard (unlikely) or to have exactly one creature to kill with Child of Alara.
Wow i misread Iname, I thought it reanimated to play. like would be reasonable for a tribal 6 mana 4/4 legend. Also Apothecary Geist needs to see another spirit in play to gain the life. Basilica Bell-Haunt does what we want.
That is definitely a problem, and not even cutting panharmonicon saves it.
As for other 3 life sources centaur safeguard was used for a bit. There's also Bartered cow now, and quite a few ohter 3 life etb creatures (mostly 5 mana 3/3 fliers)
Right Child is a green creature, we'll have it in play before we even get flash back. Good catch.
So cutting Brace for Impact, Into thin air, Goryo's Vengance, copy enchantment and Krosan groundshaker for just Smite the Monstrous looks like it works.
Smite the Monstrous does limit our later stage extensions a bit more than brace for impact did. Though we do just so happen to have only 3 power or less creatures already, so we don't need to rework anything.
We do have to be careful that we can't pump them cheaply but it looks like that's currently ok.
And managing Wormfang looks to work, though it is a bit tricky? (there might be a more efficient way?)
So under the Worldfire we need a BBM trigger to bring wormfang back, which can be done by casting wormfang, countering it, then returning it with the first BBM trigger. then we empty our hand to avoid this wormfang trigger. This gives us the Mirrorworks triggers for rebuilding. then we can put worldfire on the stack. along with a StM to bounce the Wormfang and our other 4 power creatures, we can recast Wormfang right before resolving the worldfire to hide our hand and then after worldfire we can pay for our Mirrorworks and make a Mirror of fate + perpetual timepiece to return the wormfang to play to the BBM trigger.
Eventually we will be out of BBM triggers, but we can get more by bouncing it with one copy of StM from a lower Child of Alara stage, which is cheap enough.
Edit: Speaking of Worldfire, other than the wormfang, this stage transition is fairly clean and easy.
Our only way to gain more life is Divine Congregation which we can only recast with Spellweaver Helix and our two Spider Spawnings.
But Spider spawning costs black to flashback, and we only have bayou for black and it is probably stuck in play.
Luckily we can get rid of it with Worldfire, and get it back with molderhulk (also saved by StM)
Worldfire sets our life to 1 so we better have spent all of that life from Divine Congregation.
(If we stack Divine congregation below the worldfire we won't gain any life because worldfire exiles all of our stuff and we can't get anything back until resolving below Spider Spawning.)
Rebuilding costs just a few triggers from the lower stage and then we can tap the bayou for a black to cast Spider Spawning again.
So ignoring wormfang we have
9*. Spend B to gain X life and put a WF on the stack
10. Resolve a WF to exile everything and set out life to 1, this locks flash but unlocks Bayou.
11*. lock Bayou to add B.
Goryo's Vengance would require Copy enchantment to come back in. I think Mirror Gallery lets us bounce the child while a token is still in play, without spending another card.
7a*. Spend 3 life to put x copies of StM on the stack. (TYS Copies and Psychic Battle Triggers)
7b*. resolve a StM to get x GDD
8a. resolve a StM to kill Iname and lock AG and gain 3 life.
8b. resolve a StM to kill CoA and destroy everything to lock flash and unlock AG.
We do need to be careful about keeping track of our legends and ensuring we can be set up for the next time through. These rules don't really capture that.
Without Goryo's Vengance we want to either keep the real cards in hand or have a BBM trigger waiting. Which seems a little tricky to manage? Worst case we might need Mirror gallery but still save on cards with StM.
Working around the Wormfang doesn't seem difficult as we should be able to make a token to hide the original under without too much effort once we are that far down the stack.
Hmm, what if we give them life and lifelink it back to us? so no planeswalker to get destroyed and fizzle our lifelink. we can use something like aria of flame to give them more life than we need.
Attendant of Vraska
needs an indestructable or flash Vraska, but seems easier than the Gideons.
Edit: can get a vraska, swarm's Eminence in time with Arena Rector
Kytheon+moonmist is the best I have found. being able to target any creature looks like it goes infinite if it lets us get another Worldfire.
Maybe better is some gideon and a "damage cant be prevented this turn" card. Unstable Footing
Another thought is a planeswalker to take some lifelink damage?

edit:Selkie hedge-mage cant gain life after a Worldfire
and ee=3 blows up our mimic vats so we cant imprint a cmc 3 guy.
so Reveillark + Rhox Bodygaurd/Tireless Missionaries might work?
Stormscape Battlemage is another interesting option, maybe with some sort of Upheaval effect
That is definitely a problem, and not even cutting panharmonicon saves it.
As for alternatives there's Reveillark (vesperlark), Body Snatcher, Cavalier of Night, Driver of the Dead
As for other 3 life sources centaur safeguard was used for a bit. There's also Bartered cow now, and quite a few ohter 3 life etb creatures (mostly 5 mana 3/3 fliers)

7a*. Spend 3 life to put x copies of StM on the stack. (TYS Copies and Psychic Battle Triggers)
7b*. resolve a StM to get x GDD
8a. resolve a StM to kill Iname and lock AG and gain 3 life.
