Wrath of the Skies is a key sweeper against Elves' go-wide mana dork and token plan, letting us pay enough energy to clear their small creatures (Elvish Mystic, Fyndhorn Elves, Llanowar Elves, Quirion Ranger) before they can assemble Craterhoof Behemoth or Natural Order into Atraxa, Grand Unifier. Crucible of Worlds helps rebuild our manabase against their Wasteland, letting us replay fetches from the graveyard for repeated value. Snapcaster Mage and Gandalf, Goblins' Bane are less impactful since their single-target value is weaker against the sheer card advantage and board presence Elves generates. Keep Swords to Plowshares and Force of Will in as premium answers to their biggest threats resolving.
