Mono-White Aggro curves out with small, efficient creatures like Thraben Inspector, Novice Inspector, and Fortress Kin-Guard. End the Festivities only deals 1 damage to the opponent and each creature they control, so it won't kill the 1/2 Inspectors or Kin-Guard. It is still useful for cleaning up x/1 creatures like Raffine's Informant and the 1/1 Spirit and Bird tokens from Fortress Kin-Guard and Battle Screech, while chipping the opponent for 1. Searing Blaze can kill a small creature and hit the opponent's face simultaneously, especially effective with landfall for the 3-damage mode against their 1-2 toughness creatures. Trim the slower card-filtering spells Sazacap's Brew and Highway Robbery, which cost tempo and card quality against a deck that applies early pressure. Use Searing Blaze to pick off key attackers and End the Festivities to wipe out their tokens and x/1 creatures, while racing with burn spells aimed at the opponent's face.
