Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Viscera Seer + Iron League Steed

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

Viscera Seer

Iron League Steed

How it works

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

This clever loop hinges on the front-and-back versatility of Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight, whose Isilu face grants persist to your other nontoken creatures, neatly setting up a self-sustaining cycle with Iron League Steed. When you sacrifice the Steed to Viscera Seer, its persist ability returns it with a -1/-1 counter, but its fabricate ability immediately drops a +1/+1 counter upon re-entry to annihilate that penalty via state-based actions. This leaves the Iron League Steed completely pristine and ready to be sacrificed all over again, letting you repeatedly scour your library with the Seer's scry ability while generating an endless storm of creature sacrifices, deaths, and entries.
