Kodama of the East Tree + Dimir Aqueduct + Spark Double

Kodama of the East Tree

Dimir Aqueduct

Spark Double

How it works

1. Play Dimir Aqueduct.
2. Kodama of the East Tree, Spark Double, and Dimir Aqueduct trigger.
3. Resolve the Spark Double trigger, choosing not to put anything from your hand onto the battlefield.
4. Resolve the Dimir Aqueduct trigger, returning it to your hand.
5. Resolve the Kodama of the East Tree trigger, putting Dimir Aqueduct onto the battlefield.
6. Spark Double and Dimir Aqueduct trigger.
7. Resolve the Dimir Aqueduct trigger, returning it to your hand.
8. Resolve the Spark Double token's trigger, putting Dimir Aqueduct onto the battlefield.
9. Kodama of the East Tree and Dimir Aqueduct trigger.
10. Repeat from step 5.

This brilliant loop turns the self-bouncing nature of Dimir Aqueduct into an unstoppable engine by leveraging the non-legendary status granted by Spark Double. Whenever Dimir Aqueduct enters the battlefield, its bounce trigger and the triggers from both Kodama of the East Tree and the Spark Double copy go on the stack, allowing you to continually drop and return the land. Because Kodama of the East Tree sees each entry and lets you cheat a permanent of equal or lesser mana value from your hand directly into play—which itself triggers Spark Double—the whole sequence perpetually feeds itself to generate infinite landfall triggers.
