This clever machinery hinges on Marina Vendrell acting as the central engine, using her tap ability to repeatedly lock and unlock the Spiked Corridor // Torture Pit half of the Room to endlessly manufacture fresh waves of Devil tokens. Aura of Dominion provides the critical untap loop by letting you tap those newly spawned tokens to ready Marina for her next operation, while Phyrexian Altar neatly converts your expendable Devils into the mana needed to sustain the aura's activation cost. As you feed the Devils to the altar, their own tragic demise triggers a cascade of explosive damage, effortlessly burning down your opponents with an infinite loop of fiery retribution.
