Ocelot Pride Midrange goes wide fast with Ocelot Pride tokens and Guide of Souls triggers, so single-target discard is too slow to stop the board from spiraling. Collective Brutality's -2/-2 mode cheaply picks off one small creature at a time, such as an Ocelot Pride, a Guide of Souls, or a 1/1 or 2/1 Cat token, while its discard mode can still strip a Swords to Plowshares from their hand. Bitter Triumph answers their bigger threats like Ajani, Nacatl Pariah that would otherwise run away with the game, and it also handles Amped Raptor. Keep Thoughtseize mainboard since early disruption of their proactive hand is still valuable, but swap the slower Unmask and sorcery-speed Cabal Therapy for removal that interacts with their actual board state.
