Jeskai Artifacts leans on artifact creatures and colorless value engines, making Consign to Memory strong against Urza's Saga triggers, Sewer-veillance Cam triggers, or any colorless permanent spell like Mishra's Bauble or Phyrexian Dragon Engine. Erode gives us clean removal for their key threats like Loki, God of Mischief or a resolved Kappa Cannoneer. Stifle is less impactful here since Wasteland is not a big part of their plan and their key activated abilities (Goblin Welder, Emry) aren't mana abilities but still get hit by generic removal better, so we lean into Consign to Memory and Erode instead. Force of Negation trims down since they have relatively few high-impact noncreature spells worth countering compared to our own proactive game plan.
