This ingenious loop turns a simple land drop into an engine of exponential growth by leaning on the unique nature of Dryad Arbor, which acts as both a land and a creature simultaneously. Whenever you play a land, Springheart Nantuko triggers its landfall ability to copy the Arbor, and because Dictate of Karametra doubles every mana produced when you tap those tokens for green mana, you instantly generate the exact funds needed to keep paying for the Nantuko's copies. Meanwhile, Frostcliff Siege quietly empowers your entire mechanized forest with haste, trample, and a stat boost, ensuring that this endless parade of Dryad Arbor tokens translates immediately into an overwhelming, game-ending board state.
