Wick, the Whorled Mind + Umbral Collar Zealot + Arcane Adaptation

Wick, the Whorled Mind

Umbral Collar Zealot

Arcane Adaptation

How it works

1. Cast Wick either from your hand or from the command zone by paying 3 plus commander tax, if applicable.
2. When Wick enters the battlefield, it triggers.
3. Holding priority, if you control a Snail, activate Umbral Collar Zealot by sacrificing the Snail, putting a +1/+1 counter on Umbral Collar Zealot.
4. If needed, repeat step 3 until you do not control a Snail.
5. Resolve the Wick trigger, creating a 1/1 Snail creature token.
6. When the Snail enters the battlefield as a Rat due to Arcane Adaptation, Wick triggers.
7. Repeat from step 3.

This loop relies on Arcane Adaptation to rewrite reality by declaring "Rat" as the chosen creature type, ensuring every creature you control enters as both its original type and a Rat. With that foundation set, Wick, the Whorled Mind steps onto the battlefield and triggers to birth a 1/1 Snail, which immediately masquerades as a Rat to trigger Wick all over again. You can feed that very Snail (or any other unfortunate creature or artifact) to Umbral Collar Zealot's sacrifice ability to clear your Snail control, letting Wick's delayed triggers safely resolve and restart the cycle while continuously fueling your surveil triggers.
