UW Control is loaded with counterspells (Dovin's Veto, No More Lies, Spell Snare, Censor) and card advantage (Memory Deluge, Teferi, Hero of Dominaria), so protecting your threats and disrupting their plan is key. Change the Equation's first mode counters any spell with mana value 2 or less, which covers much of their cheap interaction like Dovin's Veto, No More Lies, Spell Snare, Censor and Get Lost. Ashiok, Dream Render's -1 mills four cards and exiles their graveyard, which shuts off the flashback on Memory Deluge and Plunder the Trollshaws. Torch the Tower is weak since they run few early creatures, and extra Boomerang Basics copies are less valuable against a deck that can just recast permanents with mana to spare.
