Izzet Delver relies on Force of Will and Daze to protect Dragon's Rage Channeler and Murktide Regent while racing with Lightning Bolt; Hexing Squelcher makes our subsequent spells uncounterable and gains ward for our creatures, blunting their free countermagic. Dismember is efficient removal that can kill Dragon's Rage Channeler or an early Murktide Regent cheaply, even paying life if mana is tight. Crop Rotation and Expedition Map are cut since this matchup is about resolving threats under pressure rather than assembling specific lands. Trinisphere remains crucial, taxing their one-mana suite of Daze, Lightning Bolt, Brainstorm, and Ponder.
