This clever loop transforms graveyard utility into an explosive mana engine by weaponizing the replacement effects of Bard, King of Dale. While Dino DNA normally takes a heavy investment to make a single copy of a creature, Bard steps in to double that output into two massive 6/6 Dinosaur tokens. When those tokens enter the battlefield, the duplicated triggers from Priest of Gix flood your mana pool with six black mana—far more than enough to pay the {6} activation cost and repeat the process. Because Bard's token-doubling and Dino DNA's creation cost feed directly into Priest of Gix's self-contained mana generation, you can keep churning out infinite creature tokens and endless enters-the-battlefield triggers at will.
