Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Ashnod's Altar + Chaotic Goo

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

Ashnod's Altar

Chaotic Goo

How it works

1. Activate Ashnod's Altar by sacrificing Chaotic Goo.
2. When Chaotic Goo dies, its persist ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter on it due to its replacement effect.
3. Repeat.

This clever loop relies on Isilu, Carrier of Twilight's static ability granting persist to your other nontoken creatures, allowing Chaotic Goo to endlessly resurrect itself after meeting its demise. By feeding Chaotic Goo directly into Ashnod's Altar, you generate an endless stream of colorless mana alongside infinite sacrifice, death, and entry triggers. Meanwhile, the front face Eirdu, Carrier of Dawn sits ready to facilitate creature spells with convoke, though this particular execution lets the altar and persist loop do all the heavy lifting for an infinite resource engine.
