Enduring Vitality + Zur, Eternal Schemer + Thermopod + Yarus, Roar of the Old Gods

Enduring Vitality

Zur, Eternal Schemer

Thermopod

Yarus, Roar of the Old Gods

How it works

1. If Enduring Vitality is not a creature, activate Zur by paying 1, causing Enduring Vitality to become a creature.
2. Activate Enduring Vitality by tapping it, adding .
3. Activate Thermopod's second ability by sacrificing Enduring Vitality, adding .
4. When Enduring Vitality dies, it triggers, returning itself from your graveyard to the battlefield as an enchantment.
5. Repeat.

This cunning loop transforms an unassuming enchantment into a self-sustaining engine of sacrifice. By using Zur, Eternal Schemer to animate Enduring Vitality into a creature, you grant it the mana-producing tap ability bestowed by its own text, allowing you to tap it for white mana before feeding it to Thermopod's sacrifice ability for red mana. Because Enduring Vitality's own death trigger brings it right back to the battlefield as an enchantment rather than a creature, you can simply repeat the process ad infinitum—all while Yarus, Roar of the Old Gods eagerly watches over your creatures, ensuring all the resulting deaths and sacrifices happen without ever running out of fuel.
