Affinity is packed with colorless artifact spells like Mishra's Bauble, Mox Opal, and Tormod's Crypt, making Consign to Memory a premium answer that counters colorless spells for a single mana. Mystical Dispute punishes their blue cards like Metallic Rebuke and Preordain cheaply while still functioning as a generic counter against everything else. Cut Prismatic Ending since it cannot target land permanents like Urza's Saga and struggles to keep up with their go-wide artifact swarm, and trim slower card selection for more interaction. Wrath of the Skies remains a critical sweeper against their board of small artifact creatures.
