Kodama of the East Tree + Storm Cauldron + Springheart Nantuko

Kodama of the East Tree

Storm Cauldron

Springheart Nantuko

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 Springheart Nantuko trigger.
3. Resolve the Kodama of the East Tree trigger, choosing to put nothing onto the battlefield.
4. Resolve the Springheart Nantuko trigger, creating a 1/1 Insect creature token.
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, Springheart Nantuko triggers, creating a 1/1 Insect creature token.
10. Repeat from step 5.

This clever loop turns the self-bouncing drawback of Storm Cauldron into an engine by leveraging the cascading triggers of Kodama of the East Tree and Springheart Nantuko. Every time your land re-enters the battlefield, it triggers a cascade into the land itself via Kodama of the East Tree's ability to cheat permanents out from your hand, while Storm Cauldron ensures that tapping that same land for mana bounces it right back to where it started. Meanwhile, Springheart Nantuko capitalizes on every single one of those land drops to churn out an endless swarm of Insect tokens and creature enters-the-battlefield triggers.
