Kodama of the East Tree + Izzet Boilerworks + Zendikar's Roil

Kodama of the East Tree

Izzet Boilerworks

Zendikar's Roil

How it works

1. Play Izzet Boilerworks.
2. When Izzet Boilerworks enters the battlefield, it, Zendikar's Roil, 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 Izzet Boilerworks trigger, returning it from the battlefield to your hand.
5. Resolve the Zendikar's Roil trigger, creating a token.
6. When the token enters the battlefield, Kodama triggers, putting Izzet Boilerworks from your hand onto the battlefield.
7. When Izzet Boilerworks enters the battlefield, it and Zendikar's Roil trigger.
8. Repeat from step 4.

This clever loop transforms the bounce mechanic of Izzet Boilerworks into a self-sustaining engine by leveraging Kodama of the East Tree's triggered ability to cheat the land back onto the battlefield whenever a permanent enters. Zendikar's Roil acts as the crucial catalyst for this entire sequence, converting each land drop into an Elemental token whose entry triggers Kodama of the East Tree all over again. By continually returning Izzet Boilerworks to your hand with its own entry trigger and redepositing it using the token's arrival, you generate an endless cascade of creature tokens and landfall triggers.
