Izzet Prowess is a low-curve aggressive deck full of 1-2 toughness creatures (Dragon's Rage Channeler, Monastery Swiftspear, Slickshot Show-Off), making Brotherhood's End's 3 damage sweeper mode a great one-sided reset that also hits any Cori-Steel Cutter Monk tokens. We trim Quantum Riddler since its 5-mana body is too slow against their fast clock and its Warp mode leaves us tapped out against a deck full of cheap burn and counters like Consign to Memory. Keep Force of Negation and Subtlety at full count since they're premium against a deck that wants to jam threats and burn us out, and Subtlety can bounce a key Dragon's Rage Channeler or Slickshot Show-Off. Our Crashing Footfalls rhinos and Violent Outburst cascades provide the resilient bodies needed to race and block their small creatures.
