Whipflare sweeps Wild Nacatl and Territorial Kavu (both nonartifact creatures) cleanly while leaving our own artifact board untouched. Consign to Memory answers their colorless spells and can Replicate to counter multiple triggered abilities, though it won't stop their colored burn like Lightning Bolt or Tribal Flames. Our Engineered Explosives is also well-positioned here against their low curve. Claws of Gix, Welding Jar, and a Pithing Needle are cut since they're too passive against this aggressive, go-wide plan.
