Whipflare is excellent here, sweeping Dragon's Rage Channeler, Monastery Swiftspear, and Slickshot Show-Off (all nonartifact) while leaving our own artifact creatures untouched. Consign to Memory stops Cori-Steel Cutter's token-making trigger copies or any colorless spell they might sneak in, and its Replicate mode scales against their low-to-the-ground plan. Claws of Gix, Welding Jar, and a Pithing Needle are too slow against this hyper-aggressive matchup, so they're cut for more interaction and a sweeper.
