Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Mighty Mutanimals + Goblin Bombardment

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

Mighty Mutanimals

Goblin Bombardment

How it works

1. Activate Goblin Bombardment by sacrificing another nontoken creature that doesn't have a -1/-1 counter on it.
2. When the creature dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. When the creature enters, Mighty Mutanimals triggers, putting a +1/+1 counter on the creature.
4. Resolve the Goblin Bombardment ability.
5. Repeat.

This loop relies on the clever synergy between Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight's back face, which grants your nontoken creatures persist, and Mighty Mutanimals, which triggers whenever another creature enters the battlefield to place a +1/+1 counter on a target creature you control. By sacrificing a creature to Goblin Bombardment, you send it to the graveyard only for persist to bring it right back with a -1/-1 counter. The ensuing entry triggers Mighty Mutanimals, placing a +1/+1 counter that immediately cancels out the -1/-1 counter, resetting the creature so it can be sacrificed to Goblin Bombardment all over again for endless damage.
