Lesser Masticore + Arcbound Ravager + Mm'menon, Uthros Exile

Lesser Masticore

Arcbound Ravager

Mm'menon, Uthros Exile

How it works

1. Activate Arcbound Ravager 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 Arcbound Ravager ability.
5. Repeat.

This clever loop turns Lesser Masticore's persist mechanic into an endless engine by using Arcbound Ravager to sacrifice it before state-based actions can permanently sideline it. Whenever Lesser Masticore returns to the battlefield with a -1/-1 counter, Mm'menon, Uthros Exile steps in with a crucial +1/+1 counter trigger that instantly cancels out the penalty, allowing the persist trigger to fire over and over again. Meanwhile, Arcbound Ravager happily gobbles up each iteration, growing monstrously large while generating an infinite parade of artifact and creature sacrifices.
