Urza's Factory⁣ - Time Spiral⁣ (Uncommon)⁣ [280]

Urza's Factory taps for colourless mana and can convert seven mana into a 2/2 Assembly-Worker artifact creature token. This ability allows for late-game board presence in colourless decks or strategies that benefit from generating additional bodies. However, the high activation cost means it’s best suited for decks that can reliably manage their mana resources.
