Melira, Sylvok Outcast + Lesser Masticore + Ravenous Intruder

Melira, Sylvok Outcast

Lesser Masticore

Ravenous Intruder

How it works

1. Activate Ravenous Intruder by sacrificing Lesser Masticore.
2. When Lesser Masticore dies, its persist ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter on it due to Melira.
3. Resolve the Ravenous Intruder ability.
4. Repeat.

This clever loop centers on Lesser Masticore and its persist ability, which normally self-limits by saddling the rat with a -1/-1 counter each time it returns from the graveyard. Melira, Sylvok Outcast completely shuts down that drawback with her passive ability preventing -1/-1 counters from being placed on your creatures, allowing the Masticore to return in pristine condition endlessly. To keep the engine running, Ravenous Intruder happily acts as the sacrifice outlet, consuming the Masticore while converting each iteration into an unstoppable wave of massive power boosts and endless sacrifice triggers.
