The EPIC Storm runs Veil of Summer themselves to protect against our countermagic, making Force of Will and Flusterstorm less reliable, so Flusterstorm is trimmed since countering their payload mid-storm is often too late once they have cast Veil of Summer to make their spells uncounterable. Surgical Extraction needs a target card in a graveyard, so it is a reactive tool: once a piece like Echo of Eons or Lion's Eye Diamond is in their graveyard, it can exile every copy from their graveyard, hand, and library. Grafdigger's Cage stops spells from being cast from graveyards, which shuts off their Echo of Eons flashback. This matchup is a pure race, so our fastest route to Omniscience or a hard Show and Tell lock remains the priority plan.
