This clever loop relies on Kodama of the East Tree as your engine, translating the recursive entry of permanents into an unstoppable cascade of value. To get the gears turning, Bloodstained Mire acts as the initial catalyst, fetching a land that triggers both Kodama of the East Tree and Seed the Land. This brings Ghost Town straight from your hand to the battlefield; because Ghost Town can return itself to your hand for zero mana on any turn, you can repeatedly bounce and replay it. Every time Ghost Town and the Snake tokens from Seed the Land enter the battlefield, Kodama of the East Tree's triggered ability lets you cheat Ghost Town right back out, generating infinite landfall triggers, colorless mana, and an endless army of snakes.
