Kodama of the East Tree + Storm Cauldron + Scute Swarm

Kodama of the East Tree

Storm Cauldron

Scute Swarm

How it works

1. Play any land that enters the battlefield untapped and can tap to produce 1.
2. When the land enters the battlefield, Kodama of the East Tree and each Scute Swarm you control trigger.
3. Resolve the Kodama of the East Tree trigger, choosing to put nothing onto the battlefield.
4. Resolve the first Scute Swarm trigger, creating either a 1/1 Insect creature token or a token copy of Scute Swarm.
5. When the creature token enters the battlefield, Kodama of the East Tree triggers.
6. Holding priority, activate the land played in step 1 by tapping it, adding at least 1.
7. Storm Cauldron triggers, returning the land from the battlefield to your hand.
8. Resolve the Kodama of the East Tree trigger, putting the land from your hand onto the battlefield.
9. When the land enters the battlefield, each Scute Swarm you control triggers.
10. Repeat from step 4.

This clever loop transforms the simple act of playing a land into a self-sustaining engine by turning every entry into a cascade of triggers. As you tap your land for mana, Storm Cauldron immediately bounces it back to your hand, while Scute Swarm floods the board with a growing army of tokens. Each of those new tokens entering the battlefield satisfies Kodama of the East Tree's trigger condition, allowing you to seamlessly slide the bounced land right back onto the battlefield from your hand to repeat the process indefinitely.
