Affinity is an artifact-heavy deck, making Consign to Memory extremely effective since it counters colorless spells like Engineered Explosives, Mishra's Bauble, and Mox Opal. Hurkyl's Recall is a blowout, bouncing their entire artifact board back to hand and resetting their tempo while we keep our own resilient engine. We trim our slower graveyard/mill pieces since Affinity doesn't care about its own graveyard and racing their board state matters more.
