Circu, Dimir Lobotomist

Most mill effects measure their progress against the size of a deck; this one ignores the count entirely. The exile clause is the engine, not the disruption: every blue or black spell you cast strips the top card off a chosen library, and the static ability then locks every spell sharing that card's name out of your opponents' hands. The permanence runs in two directions, and only one of them sticks. The named cards stay banished forever, yet the casting restriction reads off the body, so the moment the 2/3 dies or gets bounced, every name it had silenced comes back online. An opponent's whole answer to the lock is to kill the wizard doing the locking, which makes the modest body the real fragility in the design. Keep it alive across a few turns and you are not racing toward an empty library; you are quietly editing your opponent's deck, snipping out whichever spell happens to be on top and dragging its duplicates down with it until the wizard falls. The deeper tension is that the spells you cast to interact with the board are the same spells fueling the lockout, so a blue-black control shell built on instants and sorceries never has to choose between answering threats and tightening the screws. The flavor lands exactly where the mechanics do: a lobotomist who edits memory rather than ending a life, holding a thought hostage only as long as he is watching.
