Kodama of the East Tree

Ghost Town

Arid Mesa

Down in the Valley

How it works

1. Fetch a land using Arid Mesa.
2. When the fetched land enters, Down in the Valley and Kodama trigger.
3. Resolve the Kodama trigger, putting Ghost Town from your hand onto the battlefield.
4. When Ghost Town enters, Kodama and Down in the Valley 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 Down in the Valley 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, Down in the Valley triggers.
10. Repeat from step 5.

This elegant engine turns a simple land drop into an infinite loop by leveraging Kodama of the East Tree as a permanent-cheating relay station. Whenever an Arid Mesa fetches a land, or Down in the Valley's second chapter creates a token, Kodama's triggered ability allows you to effortlessly cheat Ghost Town straight from your hand back onto the battlefield. Because Ghost Town can tap for colorless mana and instantly bounce itself back to your hand for zero mana on any turn, you can continuously replay it to trigger endless token creation and generate infinite resources.
