Jeskai Artifacts relies on Goblin Welder and Goblin Engineer to recur artifacts from the graveyard, so Tormod's Crypt is a sharp answer that strips away their recursion targets at an opportune moment. Pithing Needle can shut down Goblin Welder's or Goblin Engineer's activated abilities, or a key land like Urza's Saga, while Haywire Mite can exile a resolved Agatha's Soul Cauldron or The Filigree Sylex before it gets out of hand. This is a mirror-adjacent matchup where artifact count and Chalice of the Void sequencing matter immensely, so keep the swap light and lean on your existing Chalice, Force of Will, and Mox Opal package rather than overcommitting sideboard slots.
