Kodama of the East Tree + Ghost Town + Felidar Retreat + Blighted Woodland

Kodama of the East Tree

Ghost Town

Felidar Retreat

Blighted Woodland

How it works

1. Fetch a land using Blighted Woodland.
2. When the fetched land enters, Felidar Retreat and Kodama trigger.
3. Resolve the Kodama trigger, putting Ghost Town from your hand onto the battlefield.
4. When Ghost Town enters, Kodama and Felidar Retreat 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 Felidar Retreat 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, Felidar Retreat triggers.
10. Repeat from step 5.

This ingenious loop uses Blighted Woodland as a catalyst to kickstart a cascade of permanent entries, transforming a simple land search into an engine for infinite value. Once the Woodland fetches a land, Kodama of the East Tree sees that entry and uses its triggered ability to sneak Ghost Town directly onto the battlefield from your hand. Because Ghost Town's unique landfall-style arrival also triggers Felidar Retreat, you can tap the land for colorless mana and bounce it right back to your hand using its own zero-cost ability on opponents' turns. Finally, the Cat Beast tokens generated by Felidar Retreat ensure that every time Ghost Town loops back to the battlefield, Kodama of the East Tree triggers all over again to repeat the entire process seamlessly.
