Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Geralf's Mindcrusher + Thermopod

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

Geralf's Mindcrusher

Thermopod

How it works

1. Activate Thermopod by sacrificing Geralf's Mindcrusher
2. When Geralf's Mindcrusher dies, its undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
3. When Geralf's Mindcrusher enters, it triggers, causing a player to mill five cards.
4. Activate Thermopod by sacrificing Geralf's Mindcrusher
5. When Geralf's Mindcrusher dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
6. When Geralf's Mindcrusher enters, it triggers, causing a player to mill five cards.
7. Repeat.

This clever loop relies on the brilliant synergy between Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight's back face, which grants your nontoken creatures persist, and Geralf's Mindcrusher's native undying ability. By feeding Geralf's Mindcrusher into Thermopod's sacrifice outlet, you generate red mana while the creature bounces endlessly between the graveyard and the battlefield. Because undying and persist alternate placing +1/+1 and -1/+1 counters that continually cancel each other out, the mindcrusher never permanently stays dead, letting its entrance trigger mill a target player out entirely.
