Xavier Sal, Infested Captain + Agatha's Soul Cauldron + Cinderhaze Wretch + Saproling Burst

Xavier Sal, Infested Captain

Agatha's Soul Cauldron

Cinderhaze Wretch

Saproling Burst

How it works

1. Activate Xavier Sal's second ability by tapping it and sacrificing another creature, putting a +1/+1 counter on it and a fade counter on Saproling Burst.
2. Activate Saproling Burst by removing a fade counter from it, creating a Saproling creature token.
3. Activate Xavier Sal using Cinderhaze Wretch's second ability by putting a -1/-1 counter on it, untapping Xavier Sal.
4. Repeat.

This fascinating loop revolves around a clever interaction between Xavier Sal, Infested Captain and Cinderhaze Wretch's self-untapping ability, which can be granted to creatures via Agatha's Soul Cauldron. By feeding creatures to Xavier Sal's sacrifice ability, you trigger his proliferation to add counters back where they are needed, while Saproling Burst provides a steady stream of fodder and counters to keep the engine running. Every iteration swells your board with infinite creature tokens, dying triggers, and proliferate steps as you continually reset and reuse your activated abilities.
