This brilliant loop turns Jodah, Archmage Eternal into a legendary discount engine by leveraging his ability to pay a flat five-color mana cost for any spell you cast. When you sacrifice Composite Golem to generate precisely the five colors of mana needed, Enduring Renewal swoops in to intercept the metal construct from the graveyard and return it directly to your hand rather than letting it stay dead. Because Enduring Renewal is forcing you to play with your hand revealed and strictly replaces your draws, casting Composite Golem repeatedly for its alternative cost lets you continuously recycle the automaton without ever needing to draw it. This creates an endless cycle that fuels infinite sacrifice, entry, and death triggers, letting you easily build up an astronomical storm count or trigger any other payoff you might need.
