This brilliant engine relies on duplicating your commander to turn a humble bounce land into an infinite loop. By casting Irenicus's Vile Duplication, you create a nonlegendary copy of Kodama of the East Tree, giving you two triggers whenever a permanent enters the battlefield. When you play Rakdos Carnarium, its entry triggers its own ability to return itself to your hand while feeding the pair of Kodama of the East Tree triggers. As the two spirits bounce and replay the Rakdos Carnarium back and forth between your hand and the battlefield, you generate infinite landfall triggers to fuel any payoff you desire.
