Grixis Reanimator wins by cheating large threats into play early, so your top priority is disrupting their graveyard setup before they can execute their plan — Soul-Guide Lantern is essential here, exiling key pieces before they can be reanimated. Duress lets you strip reanimation spells or enablers before they resolve, buying crucial time. Disdainful Stroke catches the expensive reanimation targets or finishers they hard-cast late. Phantom Interference and Spell Snare are too narrow and situational in this matchup, and Shoot the Sheriff rarely has premium targets in a deck focused on large graveyard threats. Keep your core tempo package of Floodpits Drowner, Kaito, and Dream Beavers intact, as applying pressure forces them to act on their timeline rather than setting up freely.
