Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Zack Fair + Sifter of Skulls

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

Zack Fair

Sifter of Skulls

How it works

1. Activate Zack by paying 1 and sacrificing it.
2. When Zack dies, its persist ability and Sifter of Skulls 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 Sifter of Skulls trigger, creating a 1/1 Eldrazi Scion creature token.
5. Resolve the Zack ability from step 1.
6. Activate the Eldrazi Scion by sacrificing it, adding C.
7. Repeat.
