Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight

Yahenni, Undying Partisan

Maulfist Squad

How it works

1. Activate Yahenni by sacrificing Maulfist Squad.
2. When Maulfist Squad dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. When Maulfist Squad enters, its fabricate ability triggers, putting a +1/+1 counter on it.
4. Resolve the Yahenni ability.
5. Repeat.
