Missing sideboard cards? The full 15-card sideboard runs about $74.75.
Buy sideboard on ManapoolDimir Tempo relies on delve for Murktide Regent and escape for Nethergoyf, so Surgical Extraction and Faerie Macabre both disrupt their graveyard-fueled threats while Faerie Macabre also offers a proactive flying body. Witch Enchanter is largely dead since they run few artifacts or enchantments to destroy, and Meteor Sword is too slow and clunky against a deck built to Wasteland us and race with efficient threats. Our Thoughtseize and Aether Vial remain excellent proactive plays to strip their interaction or sidestep their countermagic like Force of Will and Daze. Keep Thalia, Guardian of Thraben in since it taxes their cantrips and countermagic significantly.
Eldrazi leans on Chalice of the Void to lock out our one and two-drops, and Disruptor Flute naming Chalice of the Void taxes future copies by 3 mana. Witch Enchanter is weak here since Eldrazi runs almost no artifacts or enchantments worth destroying outside of Chalice itself. We keep Solitude and Swords to Plowshares in since they're premium answers to Reality Smasher, Thought-Knot Seer, and Eldrazi Linebreaker. Wasteland remains crucial to strip Cavern of Souls, Eldrazi Temple, and Ancient Tomb, denying their explosive starts.
Ocelot Pride wants to chain cheap spells for value; Deafening Silence slows their engine considerably by capping them at one noncreature spell per turn, limiting noncreature spells like Swords to Plowshares and Static Prison. Erode provides a clean answer to Ajani and their aggressive creatures, destroying target creature or planeswalker at instant speed. Pre-War Formalwear and Witch Enchanter are the weakest, least impactful cards here since the opponent has few relevant artifacts/enchantments to hit and no graveyard plan worth reanimating into. Keep the removal suite intact since Solitude and Swords to Plowshares are premium against their small aggressive bodies.
