Wick, the Whorled Mind + Xenograft + Phantom Train

Wick, the Whorled Mind

Xenograft

Phantom Train

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 Phantom Train by sacrificing the Snail, putting a +1/+1 counter on Phantom Train.
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.

This loop relies on Xenograft to constantly redefine your board state, turning every creature you control into a Rat so that Wick, the Whorled Mind keeps spawning fresh Snails upon entry. Phantom Train acts as the sacrifice outlet, devouring those newly minted Snails to bulk itself up with +1/+1 counters while clearing your Snail count so Wick's trigger can fire again. By feeding the Snail token back into the Phantom Train, you establish a self-sustaining cycle of endless creature sacrifices, entering-the-battlefield triggers, and leaving-the-battlefield triggers.
