I mean: On the stack, the activation of Gerrard's Hourglass Pendant is right below the massive Spellweaver Volute triggers. After the Kaervek's Spite sweeper and computation, the activation resolve, bring things back.
Next we want to get 3 Paragon of Eternal Wilds tokens, meaning that we need to insert 3 groups of ETB triggers of Soul Foundry between each pair of Paragon of Eternal Wilds-PB/BM triggers.
We need to play Soul Foundry 3 times. Or 2 times, plus one Mirrormade. But still, between the plays, we need to take Soul Foundry back to hand, meaning a cast of Acorn Harvest and thus Kaervek's Spite, losing the Paragon of Eternal Wilds tokens created in previous plays of Soul Foundry.
We can use both Soul Foundry and Fated Infatuation to make Paragon of Eternal Wilds tokens. But how to give first kind of tokens haste but not second? If no way, how to prevent haste tokens from Fated Infatuation?
Suppose we need to play 2 creatures A and B to get their BM triggers. We play A, pushing its BM triggers. Play B, pushing its BM triggers. The stack looks like
group of B-BM
B
group of A-BM
A
Play Voracious Greatshark, then its ETB will trigger many (due to Panharmonicon and/or Dual Nature). Counter A and B, put them all in graveyard. The stack looks like
group of B-BM
group of A-BM
Resolve a B-BM, but we only get B on. Resolve down to an A-BM, we will have both A and B on battlefield, but we only leave a group of A-BM on the stack, without B-BM.
So, if I understand it correctly... both "group of Repentant Vampire-BM triggers" and "group of Firebrand Ranger-BM triggers" must each consumes a Repentant Vampire-PB trigger from below?
We consume few Repentant Vampire-PB triggers each time of transition, but then we can build MANY Repentant Vampire-PB triggers.
Currently, it is Flash along with some creature targeting abilities making haste Firebrand Ranger. But in any way, if we want haste Firebrand Ranger, we will also make haste Repentant Vampire in similar way.
EDIT: With a Mimic Vat token on battlefield, activate it without resolve. Then we play things, build abilities on the stack, and start a hyperstage transition. Use Flash to imprint Repentant Vampire on the Mimic Vat. Next, Kaervek's Spite will clean all the Mimic Vat, but for LKI the Mimic Vat will still remember the Repentant Vampire card. When after we finish things, resolve the activate ability of the Vat, and have a haste token.
And another question: why the mill-card (Tomb Robber) is so complicated (we need to discard a card), other than a simple mill-card like Shriekhorn? What is the consideration that we must discard to mill?
1. Precursor Golem seems necessary to extract the computation result. But on Repeated Reverberation, is it better or worse than Thousand-Year Storm as the number keeper (we cannot give TYS to opponent, because such TYS won't function)?
3. About Floating-Dream Zubera. We need to kill FDZ under opponent's control. This seems to be done when the computation deal too much damage on FDZ. However, at the start of computation, all Psychic Possession are gone, so we cannot draw.
...or, resolve the tap-ability of Repentant Vampire on FDZ?
4. Some ruling question. What is the timestamp of Threshold (Repentant Vampire)? The timestamp of the permanent? Or the timestamp of the last time card amount in graveyard changed? Or the timestamp of the last time the threshold turned on/off?
Common quantitative reasons may read like "we add more CARDNAME so that we can benefit more from it".
Qualitative reasons are various, including:
Quantitative reasons are bad, because you may replace the extra cards with some cards that makes a higher layer.
And, without Psychic Battle, we cannot move targeting out of Precursor Golem. wait... all Repentant Vampire can be hacked into Golems.I mean: On the stack, the activation of Gerrard's Hourglass Pendant is right below the massive Spellweaver Volute triggers. After the Kaervek's Spite sweeper and computation, the activation resolve, bring things back.
Also another problem: if the stack is like
We need to play Soul Foundry 3 times. Or 2 times, plus one Mirrormade. But still, between the plays, we need to take Soul Foundry back to hand, meaning a cast of Acorn Harvest and thus Kaervek's Spite, losing the Paragon of Eternal Wilds tokens created in previous plays of Soul Foundry.
Also, we have few mana from Mox Emerald. (There is Horn of Ramos and Tangleroot as monocolor mana source)
Also, after computation you control no Xathrid Necromancer. Fated Infatuation don't work on them.

If we further replace Vedalken Orrery by Leyline of Anticipation, can we delete March of the Machines?
