Xavier Sal, Infested Captain + Experiment Kraj + Devoted Druid + Forensic Researcher

Xavier Sal, Infested Captain

Experiment Kraj

Devoted Druid

Forensic Researcher

How it works

1. Activate Experiment Kraj using Devoted Druid'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 Forensic Researcher's first ability by tapping it, untapping Xavier Sal.
4. Repeat.

This ingenious loop turns Experiment Kraj into a versatile engine by letting it borrow Devoted Druid's self-untapping -1/-1 counter ability and Forensic Researcher's ability to untap another permanent. When you use Experiment Kraj to untap itself, it accumulates -1/-1 counters, which Xavier Sal, Infested Captain happily removes to fuel his populate ability and create endless copies of your creature tokens. Meanwhile, Forensic Researcher stands ready to untap Xavier Sal, Infested Captain each time the cycle repeats, keeping the engine running smoothly.
