This clever loop kicks off by sacrificing a Food to activate Grinding Station, sending a player's cards straight to the graveyard. That sacrifice triggers the Nuka-Cola Vending Machine, but thanks to Academy Manufactor's replacement effect, you don't just get a Treasure—you get a Clue, a Food, and a Treasure all at once. As those three tokens enter the battlefield, Grinding Station's trigger rewards you by untapping itself three separate times, leaving you ready to feed the machine again. Because the tokens you generate replace and replenish your sacrificed resources while netting you extras along the way, you can easily repeat this cycle as many times as you desire to mill your opponent out of the game entirely.
