UW Control presents a hard reactive shell. Deep-Cavern Bat is your best proactive tool — strip their key counterspells or win conditions from hand before they deploy them. Wistfulness maintains card parity against their card advantage engines. Requiting Hex provides recursive pressure that demands answers repeatedly. Day of Black Sun and Glarb, Calamity's Augur are too slow against a deck that generates value from the graveyard, and Harvester of Misery has no relevant creature targets.
