Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Solemnity + Thermopod

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

Solemnity

Thermopod

How it works

1. Activate Thermopod by sacrificing another nontoken creature without a -1/-1 counter on it.
2. When the creature dies, its persist ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter on it due to Solemnity.
3. Repeat.

This clever loop relies on Isilu, Carrier of Twilight—the backside of Eirdu, Carrier of Dawn—to grant your other nontoken creatures persist, while Solemnity steps in to completely cancel out the -1/-1 counters that would normally ruin the party. With those counters barred from being placed, you can feed any of those creatures to Thermopod to generate red mana, triggering their persist ability to return them safely to the battlefield over and over again. Because Solemnity prevents the counter from ever sticking, the recycled creature can be sacrificed indefinitely to fuel an endless engine of death, entry, and mana production.
