Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Viscera Seer + Elegant Edgecrafters

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

Viscera Seer

Elegant Edgecrafters

How it works

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

This looping sacrifice engine is centered around Isilu, Carrier of Twilight's passive grant of persist to your other nontoken creatures, which transforms Eirdu, Carrier of Dawn when you pay {B} at the start of your first main phase. By sacrificing Elegant Edgecrafters to Viscera Seer, the Edgecrafters hits the graveyard and immediately returns thanks to persist, neutralizing its new -1/-1 counter by choosing to trigger fabricate for a +1/+1 counter instead. Because Viscera Seer's sacrifice outlet lets you repeat this cycle endlessly, you generate an infinite stream of leaves-the-battlefield, enters-the-battlefield, death, and sacrifice triggers alongside infinite scry 1s to sculpt your library.
