Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Thermopod + Propeller Pioneer

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

Thermopod

Propeller Pioneer

How it works

1. Activate Thermopod by sacrificing Propeller Pioneer.
2. When Propeller Pioneer dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. When Propeller Pioneer enters, its fabricate ability triggers, putting a +1/+1 counter on it.
4. Repeat.

This clever loop is anchored by the dual nature of Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight, which grants your nontoken creatures persist once it has transformed into its twilight side. By sacrificing Propeller Pioneer to Thermopod, you generate red mana while triggering the creature's persist ability to bring it right back to the battlefield. The brilliance of Propeller Pioneer here is its fabricate ability, which places a +1/+1 counter on the creature as it enters, completely neutralizing the -1/+1 counter from persist so the cycle can repeat indefinitely.
