This clever loop transforms a simple land drop into an endlessly repeating ecosystem, using Kodama of the East Tree as the central engine that responds to tokens hitting the board. Every time a land enters, Sporemound generates a Saproling token, which in turn triggers Kodama to cheat a permanent from your hand right back onto the battlefield. To keep this cascade flowing without running out of real estate, Living Twister steps in to bounce that very same land straight back to your hand using the green mana you generated along the way.
