Stiflenought vs Jeskai Artifacts

Jeskai Artifacts relies heavily on artifact synergies like Goblin Welder, Goblin Engineer, Emry, Lurker of the Loch, and Urza's Saga, making the extra Prismatic Ending valuable since it can exile key artifacts, Emry, or other low-cost permanents converging colors. Ghost Vacuum exiles their graveyard artifacts, cutting off Goblin Welder and Goblin Engineer's recursion targets as well as Emry's reanimation fuel. Stifle can target Urza's Saga's chapter abilities or Goblin Engineer's activated ability but is situational, so trimming one copy for a more reliable exile effect is worthwhile, and Mishra's Bauble is lower-impact than the incoming answers. Keep Wasteland in to attack their Urza's Saga and other utility lands before they generate value.
