This deck is packed with colorless/devoid spells (Basking Broodscale, Glaring Fleshraker, Kozilek's Command, Devourer of Destiny), all of which Consign to Memory counters outright, so it's a premium answer here. An additional Wrath of the Skies helps catch up against Basking Broodscale, Glaring Fleshraker, and their tokens. Prismatic Ending is weak since it cannot target lands (including Urza's Saga) and their big Eldrazi cost too much to exile off our colors, and Day's Undoing refills a deck that's happy to draw more cards. Spell Snare snipes their key two-mana plays like Basking Broodscale and Malevolent Rumble.
