Kodama of the East Tree + Tireless Provisioner + Arid Archway

Kodama of the East Tree

Tireless Provisioner

Arid Archway

How it works

1. Play Arid Archway.
2. When Arid Archway enters the battlefield, it, Tireless Provisioner, and Kodama of the East Tree trigger.
3. Resolve the Kodama of the East Tree trigger, choosing not to put anything from your hand onto the battlefield.
4. Resolve the Arid Archway trigger, returning it from the battlefield to your hand.
5. Resolve the Tireless Provisioner trigger, creating a token.
6. When the token enters the battlefield, Kodama triggers, putting Arid Archway from your hand onto the battlefield.
7. When Arid Archway enters the battlefield, it and Tireless Provisioner trigger.
8. Repeat from step 4.

This crafty loop relies on a clever interplay of land bouncing and triggers to spin completely out of control. When you drop Arid Archway, its own entry trigger forces it right back to your hand, but Tireless Provisioner catches the landfall moment to generate a token. That token's arrival triggers Kodama of the East Tree, whose static-like ability immediately cheats Arid Archway back onto the battlefield from your hand to restart the cycle.
