Phyrexian Furnace is already in your mainboard and is excellent here since it can exile cards from their graveyard, disrupting Hermit Druid's mill plan or their Unearth/Animate Dead reanimation targets; keep both copies in. Annul can counter Animate Dead, an enchantment spell, denying their reanimation of Karmic Guide or other combo pieces, and it also hits Survival of the Fittest, Phyrexian Devourer and Triskelion. The extra Disenchant can answer an already-resolved Animate Dead or a Survival of the Fittest. Humility stays in because it makes all creatures lose all abilities, which shuts off Hermit Druid's activated ability and Volrath's Shapeshifter's copied text and discard ability. Prohibit also stays: its mana value cap of 2 (4 when kicked) lines up with Hermit Druid, Survival of the Fittest, Animate Dead, Cabal Therapy, Unearth and Birds of Paradise. Two Decree of Justice come out because an expensive sorcery is too slow against their fast setup. Prioritize Swords to Plowshares on Hermit Druid itself before it can activate, and hold up Counterspell for the threats they find with Survival of the Fittest.
