Mono-Blue also relies on Stasis to lock the game plus a suite of counterspells, making Pyroblast a premium answer to Counterspell or a resolved Stasis. Overload cheaply destroys their Black Vise or Powder Keg. Cursed Scroll and Rhystic Lightning are too slow and Earthquake has few relevant creature targets, so all three are cut. Keep the curve low and apply pressure fast since a locked Stasis turns off your ability to develop the board.
