Dimir Excruciator is a disruptive midrange deck designed to attack your hand with Duress and Deceit while applying pressure through Superior Spider-Man and Doomsday Excruciator, making it difficult to assemble Omniscience without protection. We bring in Spider-Sense to shield our key spells from discard and disruption and maintain card parity through their interaction suite, and Fire Magic as targeted removal to answer their threats before they apply too much pressure. Opt and Prismari Charm are trimmed because low-impact cantrips and charm utility underperform when your hand is under constant siege from discard, and you need every post-board spell to carry maximum weight. Prioritize resolving Omniscience through their disruption window—Kavaron and Uthros are your most critical pieces to protect—and be prepared post-sideboard for their Annul and Flashfreeze targeting your noncreature spells, so sequencing around their open mana is key.
