Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Viscera Seer + Peema Outrider

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

Viscera Seer

Peema Outrider

How it works

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

This clever loop turns the back side of Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight into an infinite sacrifice engine by granting persist to your other nontoken creatures, allowing Peema Outrider to repeatedly enter and die. Whenever Peema Outrider returns from the graveyard with a -1/-1 counter, its fabricate ability triggers to place a +1/+1 counter on it, which immediately neutralizes the -1/-1 counter through state-based actions. This leaves Viscera Seer free to continuously sacrifice the creature, letting you scour through your entire deck with infinite scry triggers while fueling any creature spells you wish to cast thanks to the front side's convoke-granting static ability.
