The Stone Brain

Surgical extraction, printed as a colorless artifact so any deck can run it. The lineage runs from Lobotomy through Extract and Cranial Extraction: cards that name a card, then strip up to four copies of it from a library, hand, and graveyard at once, foreclosing a combo piece or a bomb before it can be drawn. What distinguishes this version is the shape of the cost. The artifact enters for two mana and sits inert until you find your read; when you fire it, you pay two mana, tap it, and exile it from the battlefield permanently. That self-exile is the pressure valve. A Cranial Extraction was a full card and a full turn spent on a hard cast; here the threat sits on the board as a standing option, but you get exactly one activation before the piece is gone forever. The concession baked in is elegant: an opponent draws a replacement for each named card pulled from their hand, so hitting a card they were holding refunds them raw card advantage even as it removes the specific threat. That trade reframes the ability as a scalpel rather than a hammer. You are not grinding an opponent out with it; you are pre-empting a particular line, paying for the privilege with a replaceable draw on their side and a spent artifact on yours. The sorcery-speed restriction keeps it from becoming a reactive answer, which is exactly right for an effect this total.
