Mono Black Aggro floods the board with cheap threats like Forsaken Miner and Iridescent Vinelasher, and Dawn's Truce protects our life total and board from their aggressive curve while we stabilize. The extra Sunset Saboteur adds another efficient menace threat to race their low-toughness board. Requiting Hex is serviceable here since most of their creatures are mana value 2 or less, but we still trim it slightly along with Practiced Offense to make room, favoring resilience over a pump spell that doesn't affect the board when they're the ones applying pressure.
