Melira, Sylvok Outcast + Kitchen Finks + Yahenni, Undying Partisan

Melira, Sylvok Outcast

Kitchen Finks

Yahenni, Undying Partisan

How it works

1. Activate Yahenni by sacrificing Kitchen Finks.
2. When Kitchen Finks dies, its persist ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter on it due to Melira.
3. When Kitchen Finks enters, it triggers, causing you to gain 2 life.
4. Resolve the Yahenni ability.
5. Repeat.
