Dust to Dust is excellent against their artifact-heavy shell, exiling two of their key pieces like Cryogen Relic, Utrom Monitor, or Refurbished Familiar at once. Steel Sabotage can counter their affinity threats or bounce a problematic artifact to disrupt their tempo. Extract a Confession is weak since they have many similar-power creatures to sacrifice instead of their best one. Use Dispatch and Counterspell to control the pace while your card-advantage engines out-grind them.
