Mono Black Aggro floods the board with cheap, low-toughness creatures like Forsaken Miner and Nighthowl Pursuer, so a third Day of Judgment is a strong sweeper to reset the game. Disdainful Stroke is a low-priority but still-live inclusion, ready for any bigger spells they bring in from the sideboard. Their deck has essentially no noncreature spells worth countering, so Negate and one No More Lies are weak here and get trimmed in favor of the sweeper. Keep all cheap removal like Sear, Firebending Lesson, and Lightning Helix since they efficiently answer this deck's small aggressive creatures.
