This clever loop transforms Enduring Vitality into a creature using Zur, Eternal Schemer, allowing its own granted mana ability to tap for colors before feeding it to Thermopod as a sacrifice. When Enduring Vitality hits the graveyard, its built-in static revival ability triggers, returning it directly to the battlefield as an enchantment so Zur can animate it all over again. While Garna, the Bloodflame sits in reserve with flash, haste-granting prowess, and graveyard retrieval, the core engine runs seamlessly on just the interaction between Zur, Thermopod, and Enduring Vitality to endlessly churn through death and sacrifice triggers.
