This cunning loop uses Power Artifact to discount the final activation cost of Dino DNA down to a mere four mana, letting you repeatedly hatch a towering 6/6 copy of Priest of Urabrask. Every time the red-mana-generating cleric hits the battlefield, you can harvest its entrance bonus and then instantly feed it to Ashnod's Altar to turn those red mana into a surplus of colorless energy that keeps the cycle spinning. Because Power Artifact makes the dinosaur-cloning engine so remarkably efficient, you quickly generate infinite mana and an endless horde of creatures to overwhelm your opponents.
