Mono-White Aggro floods the board with small 1- and 2-toughness creatures like Novice Inspector, Thraben Inspector, Raffine's Informant, and token-makers such as Battle Screech, and Breath Weapon's 2 damage to each non-Dragon creature wipes most of this board state in one card. This is especially strong against their Battle Screech bird tokens and Lunarch Veteran chains. Annoyed Altisaur and Bonder's Ornament are too slow against their low curve and are the easiest cuts. Keep Utopia Sprawl and Arbor Elf to curve out ahead of their go-wide plan.
