Mindbreak Trap

The condition that unlocks the free cast is a window almost nobody opens by accident: an opponent casting three or more spells in a single turn is the signature of a combo deck mid-pivot, the storm count climbing, the chain assembling. That is the whole pitch. Pay , exile any number of target spells, and the engine that was about to win the game disappears off the stack with nothing it can do about it. The exile clause is what gives it teeth against decks built on recursion and graveyard loops; a countered spell goes to the bin, an exiled one is simply gone. The cost is the discipline. Drawn against fair decks that cast one or two spells a turn, it sits dead in your hand at four mana, an answer you cannot afford to deploy at the moment you would most want it. So this is a binary card by design: free and devastating against the decks that overextend on the stack, an embarrassing brick against everyone else. Its power is gated entirely behind an opponent-defined condition, the assumption that someone across the table is doing something greedy enough to give it away for nothing. When they are, few defensive spells in any color hit harder for less.
