Anarchy can blow out Opalescence, Parallax Wave, and Seal of Cleansing, which are all white permanents, in one shot, potentially unraveling the Replenish combo after it resolves. It does nothing to their blue permanents like Attunement or Decree of Silence. Tormod's Crypt proactively exiles the enchantments they discard to Attunement and Frantic Search, denying Replenish its targets before the combo turn. Sulfuric Vortex is too slow against a deck with Mana Leak and Seal of Cleansing to simply answer it, and it damages us as well. Prioritize killing them before Replenish resolves, and use the Crypt as soon as there are enchantments worth exiling in their graveyard.
