This is my set, it really works
Item: Choice Scarf
EVs: 252attack/252speed & the last 4 EVs wherever
Ice fang or Poison Fang
Choice Scarf allows it to outspeed every Pokémon in the tier
Even Scarf Gardevoir naturally, which is why I put poison fang,
So the only way to outspeed Bruxish is a naturally faster Pokémon with a scarf,
This allows it to check Toxicroak, as Sucker Punch won’t work and Linoones extreme speed won’t work. because it’s ability stops priority. U won’t need priority yourself because you will pretty much always outspeed, so u can use high powered moves like Waterfall, U can run Jolly nature, but your losing damage, I only recommend if your actually battling another scarfed bruxish. Emboar or Incineroar are great team members for it, I personally save Bruxish for late game, because it cleans up nicely. Anyway, that’s it, I went from having 1040 points in RU Pokémon Showdown, to having 1820 with that set.
