Kodama of the East Tree + Storm Cauldron + Eusocial Engineering

Kodama of the East Tree

Storm Cauldron

Eusocial Engineering

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 Eusocial Engineering trigger.
3. Resolve the Kodama of the East Tree trigger, choosing to put nothing onto the battlefield.
4. Resolve the Eusocial Engineering trigger, creating a 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, Eusocial Engineering triggers, creating a creature token.
10. Repeat from step 5.

This clever loop turns the self-bouncing penalty of Storm Cauldron into an engine of endless creation, anchored by Kodama of the East Tree's ability to cheat permanents into play whenever another permanent enters your control. As you repeatedly drop a land, Eusocial Engineering rewards each landfall with a 2/2 Robot token, which in turn triggers Kodama of the East Tree to instantly pull that same land right back out of your hand. Storm Cauldron ensures the land keeps bouncing back to your hand the moment you tap it for mana, generating infinite mana alongside an endless army of tokens.
