Spy Combo wants to flashback Dread Return or reanimate Balustrade Spy and other big creatures; we don't have graveyard hate in the sideboard to stop their self-mill engine directly, but Dust to Dust can pick off key noncreature artifacts like Overgrown Battlement's mana engine support pieces if they're artifacts, though most of their deck is creatures and lands so this is a modest upgrade at best. Vandalblast overloaded hits any artifacts they have, including their mana rocks like Lotus Petal. We trim Prismatic Strands since fog effects don't interact with their ramp-into-threats plan, and Melded Moxite since we want more interaction and less card filtering against a deck that just wants to resolve big bodies. Lean on our removal suite (Dispatch, Lightning Bolt, Galvanic Blast) to answer their threats like Troll of Khazad-dum and Generous Ent before they overwhelm us.
