Time Stop

The blunt-instrument answer to a turn going wrong. Where Stifle contests one ability and Disallow trades for one spell on the stack, this empties the entire stack with a single resolution: every spell and ability exiled at once, the active player's combat unwound, their attacks rendered meaningless, their "until end of turn" pumps and triggers all simply ending. It is a reset switch wearing the clothes of an instant, and that scope is precisely the catch. The effect reads like the ultimate counterspell, but it exiles your own things too, exiles abilities you might have wanted to keep, and does nothing to the permanents already on the battlefield. The real question is timing: the value comes not from countering a spell (a two-mana counter does that cleaner) but from blanking a turn's worth of investment when an opponent has committed attackers, fired off a chain of triggers, or built a stack tall enough that no single answer reaches it. At six mana, it asks you to read the turn and wait for the instant the opponent has overextended into both the stack and combat at once. Spent a beat early it fizzles half its value; spent at the right moment it erases a turn of work and hands it back as a discard down to hand size. A scalpel it is not; a guillotine it can be.
