Replenish dumps enchantments into the graveyard with Attunement and Frantic Search before reanimating them all at once, so graveyard disruption is extremely effective at stopping their combo cold. The extra Tormod's Crypt can exile their graveyard right before they cast Replenish, blanking the spell entirely, while Chain of Vapor can bounce a resolved Opalescence or Parallax Wave to buy a critical turn. Arcane Denial is weak since drawing them cards accelerates their combo assembly, so it comes out in favor of proactive graveyard disruption.
