Cursed Totem shuts off Basking Broodscale's adapt ability and Eldrazi Spawn sacrifice abilities, slowing their mana and growth engine significantly. Metallic Rebuke is live against Emrakul, the Promised End and Devourer of Destiny, buying time against their biggest threats. Claws of Gix is weak here since this isn't a fast race and they have little incidental life pressure to answer, while Emry is a worse topdeck against a deck full of colorless permanents it can't easily interact with. Keep the rest of the artifact shell intact since Tormod's Crypt and Engineered Explosives are already well-positioned against their graveyard and permanent-based gameplan.

Consign to Memory counters colorless spells and triggered abilities. That covers their colorless artifacts like Mishra's Bauble and Nihil Spellbomb, plus triggers such as Stitcher's Supplier's mill trigger and Orcish Bowmasters' enters trigger. It cannot answer Street Wraith: the card is black, and its cycling is an activated ability. Cursed Totem is not part of the plan. None of their creatures have activated abilities on the battlefield, and Orcish Bowmasters' amass is a triggered ability, so Totem would do nothing here. Tormod's Crypt is a one-shot answer against a deck that mills itself constantly and rebuys from the graveyard via Detective's Phoenix bestow and Nethergoyf escape, so a single Crypt activation won't keep up; trim to focus on the proactive game plan. One Claws of Gix comes out since this matchup is more about racing their aggressive curve than gaining incremental life. Keep Kappa Cannoneer and Pinnacle Emissary as the primary clock against their disruption suite.

Metallic Rebuke counters their key spells like Wrath of the Skies or a planeswalker unless they pay 3, and with our artifact-heavy board it's often cheap to cast through improvise. Note that Supreme Verdict can't be countered, so don't plan around Rebuke to stop it. Mystical Dispute costs only {U} against their many blue spells (Teferi, Time Raveler; Narset, Parter of Veils; Jace, the Mind Sculptor; their own Consign to Memory), though like Rebuke it only counters the spell unless they pay {3}. Tormod's Crypt is weak since their graveyard plan is minimal beyond Day's Undoing shuffling away. Claws of Gix is cut since this is a grindy matchup decided by resolving threats through their countermagic and wraths, not life totals.
