Kodama of the East Tree + Ghost Town + Arid Mesa + Dragonback Assault

Kodama of the East Tree

Ghost Town

Arid Mesa

Dragonback Assault

How it works

1. Fetch a land using Arid Mesa.
2. When the fetched land enters, Dragonback Assault and Kodama trigger.
3. Resolve the Kodama trigger, putting Ghost Town from your hand onto the battlefield.
4. When Ghost Town enters, Kodama and Dragonback Assault trigger.
5. Holding priority, activate Ghost Town's first abiltiy by tapping it, adding C.
6. Activate Ghost Town's second ability by paying 0, returning it from the battlefield to your hand.
7. Resolve the Dragonback Assault from step 4, creating a token.
8. When the token enters, Kodama triggers, putting Ghost Town from your hand onto the battlefield.
9. When Ghost Town enters, Dragonback Assault triggers.
10. Repeat from step 5.

This fascinating loop relies on Kodama of the East Tree as its mechanical heart, using its triggered ability to cheat permanents into play whenever another permanent enters your control. By leveraging the landfall ability of Dragonback Assault, every time a land or a token enters, Kodama triggers to pull Ghost Town straight from your hand. Ghost Town is uniquely suited for this because its zero-mana return ability can be activated on an opponent's turn to bounce itself back to hand, while its tap ability still manages to generate infinite colorless mana in the process. Finally, Arid Mesa serves as the critical catalyst to kick off the entire sequence by fetching a land on that same opponent's turn, allowing you to establish a perpetual engine of tokens, mana, and landfall triggers.
