Return of the Mole Man

Green landfall decks already want to churn out extra land drops for their own sake, which is what makes this a nearly-free bolt-on: each land that resolves offers to mill two, so the graveyard fills as a byproduct of doing what the deck was going to do anyway. The payoff reads that graveyard's permanent count directly, converting the pile into a wide swarm of Moloid tokens. What ties the halves together is that the milling is not waste; every permanent card sent from library to bin is a downpayment on the sacrifice ability's X. The Moloids then extend the loop, milling on attack, so a board that survives keeps topping off a graveyard other green payoffs can feed on even after the enchantment is gone. The sorcery-speed restriction on that ability answers an obvious timing question: you cannot flash out a token army in response to a board wipe or at an opponent's end step, which stops a two-mana enchantment that snowballs unattended from also functioning as an instant-speed reset. And because the landfall mill is a "may," deck-out is optional; once the library thins, you decline the trigger and cash in the pile you have already assembled. The floor is a slow accumulation of fodder, but the ceiling is a board built entirely from cards you were never going to cast.
