Melira, Sylvok Outcast + Umbral Collar Zealot + Lesser Masticore

Melira, Sylvok Outcast

Umbral Collar Zealot

Lesser Masticore

How it works

1. Activate Umbral Collar Zealot 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 Umbral Collar Zealot ability
4. Repeat.
