Trinisphere is devastating against Jeskai Artifacts' entire zero and one-mana shell (Lotus Petal, Mishra's Bauble, Mox Opal, Chromatic Star), taxing everything to three mana and badly disrupting Goblin Welder and Emry, Lurker of the Loch's cheap synergies. Disruptor Flute can name Goblin Welder or Goblin Engineer to make their abilities unusable and tax their casting costs, striking at their core engine pieces. Clarion Conqueror is already excellent here, shutting off activated abilities from Goblin Welder, Goblin Engineer, Emry, and their artifacts entirely. Cut your own fast-mana artifacts since giving them nothing extra to interact with matters little, and this is a grindier disruption fight where taxing effects outperform speed.
