Affinity relies heavily on cheap artifacts like Mishra's Bauble, Mox Opal, and Urza's Saga tokens, all of which die to Abrupt Decay at mana value 3 or less, including Kappa Cannoneer and Pinnacle Emissary. Outland Liberator can sacrifice to blow up Urza's Saga or any troublesome artifact, which is exactly the kind of proactive hate this matchup wants. Kraul Harpooner trades well with their small artifact creatures and adds another cheap body to our board. We trim our slowest, most combo-only pieces since this matchup is often decided by tempo and artifact disruption rather than grinding card advantage.
