Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Grimgrin, Corpse-Born + Maulfist Squad

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

Grimgrin, Corpse-Born

Maulfist Squad

How it works

1. Activate Grimgrin 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 Grimgrin ability.
5. Repeat.
