Mono-White Aggro curves out with a swarm of small 1- and 2-toughness creatures (Thraben Inspector, Novice Inspector, Raffine's Informant, token-makers like Battle Screech), making Fiery Cannonade's 2 damage sweep extremely efficient at resetting their board. Electrickery, overloaded for just {1}{R}, is a cheaper but narrower sweep: 1 damage to each creature you don't control kills Battle Screech's 1/1 Bird tokens, Lunarch Veteran, and an unbuffed Raffine's Informant, but the 1/2 Inspectors and Fortress Kin-Guard survive it. Alms of the Vein is the weakest card to cut since this is a tempo race where sweeping their board matters far more than a slow 3-life swing against an aggressive white deck. Keep the core removal suite (Lightning Bolt, Fiery Temper) focused on bigger threats like Leonardo, Big Brother and Salt Road Packbeast that survive the sweepers.
