Memoricide

The descendant of Lobotomy that finally got the wording right. Surgical name-stripping had existed for years, but it kept tripping over the question of where a card could hide: pull the copies from the library and you missed the one in hand, name the wrong card and you whiffed entirely. This consolidates the search into a single sweep of graveyard, hand, and library at once, then exiles every match and shuffles the player's deck back together. The effect is total within the named card: if you call it correctly, that name is gone from the game for that player, with no recursion and no tutor to fetch it back. What makes the design coherent is its narrowness. It costs four mana at sorcery speed, does nothing to the board, and trades a full turn for information you have to be right about: against a deck built around a single engine or combo piece, that trade is decisive, and against a deck with no such linchpin, you have spent four mana to look at someone's library. It is a scalpel, not a hammer, and it rewards knowing the opponent's deck better than the opponent's draws. The card asks one question (what cannot this deck win without?) and answers it permanently.
