Izzet Delver is a fast tempo deck backed by Force of Will and Daze, so free interaction is the main obstacle to landing our reanimation spells — Surgical Extraction post-Therapy or Thoughtseize can strip a card they're relying on to rebuild, though its main job here is protecting our own discarded reanimation targets from their maindeck graveyard hate isn't present, so it mostly comes in as a proactive discard-adjacent disruption piece. Chain of Smog helps clear Force of Will and Daze from their hand before we commit our real threats. Cut the top-heavy, situational cards (Raph & Mikey, Borborygmos) since this matchup is a straight race decided in the first few turns — get Griselbrand or Atraxa down as early as possible to stabilize against Dragon's Rage Channeler and Murktide Regent. Wasteland can strand us on colored mana, so sequence Lotus Petal and Dark Ritual carefully to play around a blown-up land.
