When the fetched land enters, Springheart Nantuko and Kodama trigger.
Resolve the Kodama trigger, putting Ghost Town from your hand onto the battlefield.
When Ghost Town enters, Kodama and Springheart Nantuko trigger.
Holding priority, activate Ghost Town's first abiltiy by tapping it, adding C.
Activate Ghost Town's second ability by paying 0, returning it from the battlefield to your hand.
Resolve the Springheart Nantuko from step 4, creating a token.
When the token enters, Kodama triggers, putting Ghost Town from your hand onto the battlefield.
When Ghost Town enters, Springheart Nantuko triggers.
Repeat from step 5.
This elegant loop transforms a humble landfall trigger into an engine of endless replication, powered by the recursive dropping of Ghost Town. As you fetch a land with Bant Panorama, Kodama of the East Tree sees that entry and uses its triggered ability to cheat Ghost Town directly into play from your hand. That new entry instantly fuels Springheart Nantuko's landfall ability to copy a creature and triggers Kodama all over again, creating a self-sustaining loop. By tapping Ghost Town for mana before bouncing it back to your hand with its own zero-cost ability on opponent's turns, you endlessly churn out colorless mana, creature tokens, and enters-the-battlefield triggers.
