Affinity Stompy vs Jeskai Artifacts

Jeskai Artifacts is a mirror-like matchup built around Goblin Welder and Goblin Engineer recursion plus Emry, Lurker of the Loch value, so extra copies of Kappa Cannoneer give you a resilient Ward 4 threat that grows every time an artifact enters and dodges their Lightning Bolt and Abrade removal. Tormod's Crypt is a free way to strip their graveyard, shutting off Goblin Engineer's discard-then-reanimate plan and Emry's mill-based recursion. Consign to Memory stops their colorless artifact spells (Mishra's Bauble, Sewer-veillance Cam, Chromatic Star) for a single mana. Sink into Stupor is weaker in a mirror where both sides rebuild artifacts quickly, so trim it along with the narrow one-ofs.
