This engine turns your enchantments into a self-sustaining sacrifice loop by leveraging Zur, Eternal Schemer's ability to animate Enduring Vitality into a creature. Once animated, Enduring Vitality taps for mana thanks to its own granted ability, which can be supplemented by Fervor keeping things hasty if needed, and is then immediately sacrificed to Thermopod to generate red mana and trigger its death return. Because Enduring Vitality's death trigger resurrects it safely as an enchantment rather than a creature, it bypasses permanent loss and resets cleanly to be animated all over again by Zur, Eternal Schemer.
