Wick, the Whorled Mind + Altar of Dementia + Xenograft

Wick, the Whorled Mind

Altar of Dementia

Xenograft

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 Altar of Dementia by sacrificing the Snail, causing target player to mill cards equal to the Snail's power.
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 Xenograft, Wick triggers.
7. Repeat from step 3.
