Discontinuity (M21-48) is a blue instant from Core Set 2021. It ends the turn when it resolves, exiling the stack, removing combat, causing cleanup and discarding as specified, and costs less to cast during your turn. Its primary role is a tempo-reset or interaction piece that can negate an opponent’s ongoing actions by skipping the remainder of the turn.
