This clever loop transforms a simple land drop into an engine of endless creation by playing on Kodama of the East Tree's triggered ability to cheat permanents into play. Every time a land enters the battlefield, Nesting Dragon dutifully generates a Dragon Egg token, which in turn triggers Kodama of the East Tree to let you drop a permanent of equal or lesser mana value from your hand. Living Twister acts as the crucial pressure valve, using the mana generated by your land to bounce that very same land right back to your hand so Kodama of the East Tree can loop it infinitely.
