Xavier Sal, Infested Captain + Experiment Kraj + Cinderhaze Wretch + Aphetto Alchemist

Xavier Sal, Infested Captain

Experiment Kraj

Cinderhaze Wretch

Aphetto Alchemist

How it works

1. Activate Experiment Kraj using Cinderhaze Wretch's second ability by putting a -1/-1 counter on it, untapping it.
2. Activate Xavier Sal's first ability by tapping it and removing a -1/-1 counter from Experiment Kraj, creating a copy of any creature token you control.
3. Activate Experiment Kraj using Aphetto Alchemist's ability by tapping it, untapping Xavier Sal.
4. Repeat.

This clever engine harnesses the borrowed potential of Cinderhaze Wretch to endlessly untap Experiment Kraj by peppering it with -1/-1 counters. Xavier Sal, Infested Captain then steps in to strip those counters away with his tap ability, weaponizing the removal to repeatedly populate your battlefield with fresh copies of any creature token you control. Meanwhile, Aphetto Alchemist's untap ability—borrowed by Experiment Kraj—resets Xavier Sal's tap state after each iteration, keeping the loop spinning indefinitely.
