Xavier Sal, Infested Captain + Experiment Kraj + Cinderhaze Wretch + Seeker of Skybreak

Xavier Sal, Infested Captain

Experiment Kraj

Cinderhaze Wretch

Seeker of Skybreak

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 Seeker of Skybreak's ability by tapping it, untapping Xavier Sal.
4. Repeat.

This clever setup relies on Experiment Kraj absorbing the activated abilities of Cinderhaze Wretch and Seeker of Skybreak while they each carry a +1/+1 counter. You begin by tapping Experiment Kraj to place a -1/-1 counter on itself, using Cinderhaze Wretch's self-untap ability to ready it once more. Xavier Sal, Infested Captain then steps in to remove that newly placed -1/-1 counter to populate, creating a fresh copy of any creature token you control. Finally, Experiment Kraj uses Seeker of Skybreak's ability to untap Xavier Sal, Infested Captain, looping the sequence to generate infinite creature tokens and endless enters-the-battlefield triggers.
