Jeskai Artifacts relies heavily on graveyard recursion via Goblin Welder, Goblin Engineer, and Emry, Lurker of the Loch to reanimate artifacts, so graveyard hate is extremely potent. Rest in Peace exiles their graveyard on entry and shuts off Goblin Welder/Engineer loops and Emry's activated ability entirely. Endurance can be evoked for free to reset their graveyard again if it gets rebuilt, denying repeated value from Mishra's Bauble mills and Emry's self-mill. Solitude is a weaker fit since they have few must-answer creature threats early, and Wrath of the Skies is often too slow against their artifact-based value engine that doesn't rely on a wide creature board.
