Affinity is a combo-artifact deck that assembles powerful threats through Urza's Saga tokens and Kappa Cannoneer, with Mox Opal enabling explosive mana and Weapons Manufacturing flooding the board with artifact creatures. Consign to Memory is your premier answer here, exiling Saga constructs, Kappa Cannoneer, or Emry at instant speed while being essentially uncounterable with enough artifacts in play on their side — time your casts to maximize the free-exile mode. Counterspell and Force of Negation protect against their best threats and deny Metallic Rebuke blowouts on your sweepers. Prismatic Ending handles most of their low-cost permanents cleanly, and Teferi, Time Raveler's static ability removes their ability to hold up Metallic Rebuke shields. Sweepers lose value because their board refills quickly through Saga, so prioritize countering key pieces over trying to clean up with wraths.
