Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Zack Fair + Pawn of Ulamog

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

Zack Fair

Pawn of Ulamog

How it works

1. Activate Zack by paying 1 and sacrificing it.
2. When Zack dies, its persist ability and Pawn of Ulamog triggers.
3. Resolve the persist trigger, returning Zack from your graveyard to the battlefield without a -1/-1 counter on it due to its replacement effect.
4. Resolve the Pawn of Ulamog trigger, creating a 0/1 Eldrazi Spawn creature token.
5. Resolve the Zack ability from step 1.
6. Activate the Eldrazi Spawn by sacrificing it, adding C.
7. Repeat.
