Kodama of the East Tree + Storm Cauldron + Nesting Dragon

Kodama of the East Tree

Storm Cauldron

Nesting Dragon

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 Nesting Dragon trigger.
3. Resolve the Kodama of the East Tree trigger, choosing to put nothing onto the battlefield.
4. Resolve the Nesting Dragon trigger, creating a 0/2 Dragon Egg 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, Nesting Dragon triggers, creating a 0/2 Dragon Egg creature token.
10. Repeat from step 5.

This loop relies on Kodama of the East Tree as your engine, translating every new permanent into a cascade that drops permanents of equal or lesser mana value right back onto the battlefield from your hand. Nesting Dragon turns this loop into a self-sustaining ecosystem by flooding your board with Dragon Egg tokens on every single landfall trigger, which in turn continuously re-triggers Kodama of the East Tree's ability. Finally, Storm Cauldron keeps the momentum going by bouncing your lands straight back to your hand the moment they tap for mana, ensuring you always have a land ready in hand to replay and keep the entire chain moving infinitely.
