This matchup is a race against their enchantment engine, so Annul is excellent at stopping a key enchantment spell like Enchantress's Presence, Solitary Confinement, or Opalescence before it locks the game up. Tormod's Crypt can exile their graveyard to blank Krosan Reclamation and Replenish plans if they board that way. Smother is effectively dead because Argothian Enchantress has shroud and can't be targeted, and Sickening Dreams is not worth the card against their mostly 0/1 Enchantress bodies, so those come out along with Foil. Diabolic Edict gets around Argothian Enchantress's own Shroud because it targets the player rather than the creature, though it can't be cast on them while Solitary Confinement gives them shroud. Nausea can cheaply wipe their 0/1 Enchantresses without targeting. Keep Duress and Impulse in to proactively strip or dig past their key pieces.
