Dimir Tempo leans on Force of Will, Daze, and Thoughtseize to disrupt and protect threats like Murktide Regent and Tamiyo; Hexing Squelcher makes our spells uncounterable by Force of Will/Daze and gives our own creatures ward, directly undercutting their interaction plan. Tormod's Crypt disrupts Murktide Regent's delve fuel and slows Nethergoyf/Barrowgoyf growth by denying graveyard resources. Crop Rotation and Expedition Map are cut since we have no urgent toolbox land need against a tempo deck and want proactive disruption instead. The core prison/ramp plan with Trinisphere and Karn stays, since Trinisphere taxes their cheap interaction severely.
