Affinity is a combo-adjacent artifact deck that can win very quickly through Kappa Cannoneer going wide, Urza's Saga tokens, or a Weapons Manufacturing chain with Mox Opal mana. Trinisphere is your most impactful card — it essentially halts their zero-cost artifact package (Mox Opal, Mishra's Bauble, Tormod's Crypt, Welding Jar) and makes every spell they cast cost at least three mana, which cripples their tempo. Fracturing Gust is a one-sided sweeper that destroys all their artifacts and enchantments while gaining you life, a devastating blow if you can land it at the right moment. Surgical Extraction can follow up on an Emrakul hit or a destroyed Urza's Saga to deny the remaining copies. Your large creatures simply outsize everything they produce, so maintaining card quality by shaving the two weakest lands and Slumbering Trudge is sufficient.
