This clever engine works by leveraging Clock of Omens to repeatedly untap Immovable Rod, which triggers a dungeon venture every single time it becomes untapped. While the Rod drives the engine by letting you cycle through the Lost Mine of Phandelver, Academy Manufactor and Doubling Season work behind the scenes to radically multiply your output whenever a token creation event occurs. Because Clock of Omens only requires any two untapped artifacts to pay its cost—using the very tokens the Rod's dungeon rooms help generate—you can loop this process indefinitely to flood the board with near-infinite Clue, Food, and Treasure tokens while draining your opponents out of the game.
