Izzet Affinity floods the board with cheap artifacts (Mox Opal, Lotus Petal, Seat of the Synod, Urza's Saga constructs) to enable Kappa Cannoneer and Emry, Lurker of the Loch; Force of Vigor can two-for-one destroy their key artifacts for free by exiling a green card, swinging tempo hard. Damping Sphere taxes their multi-spell artifact turns and caps big mana off lands tapped for 2+, slowing their Ancient Tomb-fueled starts. We trim Pithing Needle since their threats aren't activated-ability reliant in the way Needle punishes best, and cut one copy of Disruptor Flute net since Mox Opal/Urza's Saga taxing is useful but we want more proactive removal. Keep Wasteland in to blow up Urza's Saga and Seat of the Synod before they complete the Saga chain.
