The Rock's Pernicious Deed is the single biggest threat to our board of animated enchantments, so Seal of Cleansing gives us a proactive way to destroy it before it blows up our Opalescence-powered creatures. Abeyance protects our combo turn from Cabal Therapy or an instant-speed answer, letting Replenish resolve and our enchantment-creatures survive long enough to attack. Mana Leak is mediocre against a grindy midrange deck that can simply wait us out or pay the tax with Wall of Roots mana, and Intuition's extra selection matters less than having hard answers to Pernicious Deed. Swords to Plowshares remains important for Ravenous Baloth and Krosan Tusker.
