Affinity relies heavily on artifacts like Mox Opal and Kappa Cannoneer, plus the Weapons Manufacturing enchantment, making Nature's Claim excellent at destroying key mana accelerants or engine pieces, even though it gives them 4 life. The second Vexing Bauble (we run one main) punishes their free spells: Mishra's Bauble, Mox Opal, Welding Jar, Tormod's Crypt, and Claws of Gix all cost {0}, so casting them spends no mana and Bauble counters them. Pithing Needle can shut down activated abilities like Emry's graveyard-casting ability or Engineered Explosives' sacrifice ability. We trim Sowing Mycospawn and Emrakul since this matchup is fast and we'd rather have cheap interaction than ramp into a slow bomb, and cut a Talisman since we want more actual disruption pieces in the deck.
