Jeskai Artifacts relies on a low-curve artifact shell (Mishra's Bauble, Lotus Petal, Mox Opal) plus Urza's Saga assembling threats, so Engineered Explosives set to destroy X=0 or X=1 permanents can wipe their swarm of cheap artifacts and 1-drop creatures like Goblin Welder and Emry. Consign to Memory is excellent here, countering colorless spells (Sewer-veillance Cam, many of their artifact spells) and any triggered ability, giving you cheap, efficient interaction against their engine pieces. Stifle can technically target Urza's Saga's chapter triggers or Emry's activated ability, but Consign to Memory covers more of their gameplan for the same mana investment, so we lean into the more flexible option. Force of Will and Force of Negation remain vital to stop Urza's Saga assembly and key artifact spells before they resolve.
