Xavier Sal, Infested Captain + Experiment Kraj + Devoted Druid + Kelpie Guide

Xavier Sal, Infested Captain

Experiment Kraj

Devoted Druid

Kelpie Guide

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 Kelpie Guide's first ability by tapping it, untapping Xavier Sal.
4. Repeat.

This fascinating engine transforms Experiment Kraj into an ultimate multi-tool by stacking abilities onto a single creature. With Devoted Druid's self-untapping power borrowed onto Experiment Kraj, you can continuously pump out -1/-1 counters to untap it endlessly, while Xavier Sal, Infested Captain acts as the engine's catalyst by consuming those very counters to populate your board. Finally, Kelpie Guide steps in to untap Xavier Sal whenever tapped, allowing you to seamlessly loop the entire process for an endless horde of token copies.
