This opponent is entirely colorless, so Veil of Summer's hexproof-from-blue-and-black and Spell Pierce's generic tax are largely wasted, while Consign to Memory's replicate ability to counter multiple colorless spells for one mana each is excellent against their Karn, the Great Creator, Grim Monolith, The One Ring, and Ugin, Eye of the Storms. Carpet of Flowers is dead against this matchup since it only triggers off Islands the opponent controls, and since this opponent fields none, leave it in the sideboard; the slot instead goes to the extra Consign to Memory copies plus keeping Flusterstorm out, since this deck's threats are mostly cast as sorcery-speed artifacts and planeswalkers rather than a storm-style chain you need to counter-war through. Trinisphere and Chalice-adjacent mana denial can slow your Ancient Tomb-fueled starts, so prioritize resolving Show and Tell or Omniscience before they land Urza's Saga into a lock piece. Force of Will and Brainstorm remain your core engine and should stay at full count to find and protect your win conditions.
