Kodama of the East Tree + Cloudstone Curio + Sakashima the Impostor

Kodama of the East Tree

Cloudstone Curio

Sakashima the Impostor

How it works

1. Play the nonartifact permanent in your hand.
2. When it enters the battlefield, Cloudstone Curio and both copies of Kodama of the East Tree trigger.
3. Resolve the Cloudstone Curio trigger, returning the other nonartifact permanent from the battlefield to your hand.
4. Resolve the first Kodama of the East Tree trigger, putting the permanent you returned in step 3 from your hand onto the battlefield.
5. When that permanent enters the battlefield, Cloudstone Curio and the second Kodama of the East Tree trigger.
6. Resolve the Cloudstone Curio trigger, returning the permanent you played in step 1 from the battlefield to your hand.
7. Resolve the Kodama of the East Tree trigger from step 5, declining to use it unless desired.
8. Resolve the remaining Kodama of the East Tree trigger from step 2, putting the permanent you returned in step 6 from your hand onto the battlefield.
9. Repeat from step 2 any number of times.
10. This combo results in Infinite ETB and Infinite LTB if a permanent involved is a creature, and/or Infinite landfall triggers if it is a land.

This elegant engine turns a simple loop of permanents into an overwhelming cascade of triggers by weaponizing the interaction between cloned triggers. With Sakashima the Impostor copying Kodama of the East Tree, you control two copies of the legendary spirit, allowing any entering permanent to trigger both of their abilities. As you bounce and replay your permanents using Cloudstone Curio, the overlapping Kodama triggers catch each other on the rebound to endlessly cheat cards from your hand onto the battlefield.
