6. Resolve the Kodama of the East Tree trigger, putting Boros Garrison onto the battlefield.
7. The Kodama of the East Tree token and Boros Garrison trigger.

19. Resolve the Boros Garrison trigger, returning it to your hand from the battlefield.

This clever loop hinges on duplicating your commander with Irenicus's Vile Duplication so that you control two instances of Kodama of the East Tree, bypassing the legendary rule and doubling up on entry triggers. When you play Boros Garrison, its own bounce ability returns it to your hand, while its entry triggers the pair of Kodamas to drop it right back onto the battlefield. Because one Kodama can trigger off the other's cheated permanent and vice versa, this creates an infinite self-sustaining loop of land drops and returns, generating infinite landfall triggers to fuel any payoff you desire.
