Disdainful Stroke is live against their higher-cost artifact threats and value engines. The extra Erode gives flexible removal for any creature threats they land. Spell Snare has few targets since most of their key artifacts cost 3 or more, and Fatehold Charm's bounce mode is mostly dead against noncreature artifact permanents; keep our two copies of Pinnacle Starcage in since the exile effect disrupts their own artifact synergies like Simulacrum Synthesizer, and Day of Judgment remains useful versus any creature tokens they generate.
