Lesser Masticore + Yahenni, Undying Partisan + Mm'menon, Uthros Exile

Lesser Masticore

Yahenni, Undying Partisan

Mm'menon, Uthros Exile

How it works

1. Activate Yahenni by sacrificing Lesser Masticore.
2. When Lesser Masticore dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. When Lesser Masticore enters, Mm'menon triggers, putting a +1/+1 counter on Lesser Masticore.
4. Resolve the Yahenni ability.
5. Repeat.

This elegant loop turns Yahenni, Undying Partisan into a relentless sacrifice outlet by feeding it Lesser Masticore over and over. Each time Lesser Masticore perishes and returns via its persist ability, it enters with a -1/-1 counter, but Mm'menon, Uthros Exile steps in with its artifact-triggered ability to place a +1/+1 counter on the Masticore, neatly neutralizing the -1/-1 counter through state-based actions. This interaction lets you cycle Lesser Masticore infinitely to farm death and sacrifice triggers while steadily pumping your creatures.
