Circu, Dimir Lobotomist

Gameplan

Circu is a UB control commander who exiles cards from libraries every time you cast a blue or black spell, slowly grinding opponents toward an empty deck while locking them out of casting copies of exiled cards. You play a reactive control game—counter, remove, draw—and let incidental triggers stack mill while you assemble a dedicated mill or deck-out win.

Key Cards

• Maddening Cacophony — Mills half of every opponent's library when kicked, the fastest swing in a Circu deck.
• Bruvac the Grandiloquent — Doubles all your mill, turning incidental Circu/spell triggers into lethal deckouts.
• Fraying Sanity — Each end step it doubles a target's mill, compounding with every Circu trigger.
• Mesmeric Orb — Repeatable mill engine that hits the whole table independent of your spellcasting.
• Jace, Wielder of Mysteries — Converts your own potential deckout into a clean win and supports a mill-into-victory plan.
• Counterspell — Cheap blue interaction that protects your engine and triggers Circu's exile.

Upgrade Path

Add fast mana (Sol Ring, Dimir Signet, Talisman of Dominance) and the premium counter/removal suite to ensure you survive long enough to win the long game. Tighten the mill package around Bruvac, Maddening Cacophony, and Fraying Sanity, and include Archive Trap/Glimpse the Unthinkable for burst; protect Circu with cheap regenerators or hexproof effects. If mill stalls, splash a backup win like Thassa's Oracle plus self-mill to guarantee a deck-out finish.
