Dimir Midrange leans on Kaito, Bane of Nightmares and Enduring Curiosity as resilient engines, so Duress proactively strips Requiting Hex, Bitter Triumph, or countermagic before they can protect those threats. Stir Up Trouble's extra cost is clunky against their efficient removal-light curve, and the 6-mana Rottenmouth Viper is too slow against their disruption-heavy plan. The Ooze provides incremental value and graveyard hate against their modest graveyard synergies. Keep the full removal suite to answer Kaito and Floodpits Drowner.
