Luminous Broodmoth + Lesser Masticore + Ravenous Intruder

Luminous Broodmoth

Lesser Masticore

Ravenous Intruder

How it works

1. Activate Ravenous Intruder by sacrificing Lesser Masticore.
2. When Lesser Masticore dies, its persist ability triggers if it didn't have a -1/-1 counter, and Luminous Broodmoth triggers if Lesser Masticore didn't have flying.
3. Resolve the persist trigger, if applicable, returning Lesser Masticore from your graveyard to the battlefield with either a -1/-1 counter on it.
4. Resolve the Luminous Broodmoth trigger, if applicable, returning Lesser Masticore from your graveyard to the battlefield with a flying counter on it if Lesser Masticore is still in your graveyard.
5. Resolve the Ravenous Intruder ability.
6. Repeat.
