This elegant prison lock weaponizes Stasis to freeze the board while keeping your own resources fluid. Normally, Stasis would starve you of mana by skipping everyone's untap steps and demanding upkeep payments, but Urza, Lord High Artificer completely bypasses this drawback by letting you tap your artifacts directly for blue mana. To ensure you always have enough artifacts to tap without falling behind, Court of Vantress steps in at the beginning of your upkeep to duplicate your best utility artifacts, providing a steady stream of new targets for Urza to tap to pay Stasis's upkeep cost turn after turn.
