Sableye as a
counter. Sableye is able to effortlessly switch into any of Braviary's attacks, being immune to two of them, and force it out, allowing Sableye to either Knock Off the incoming pokemon, or Wisp it.
252 Atk Braviary Brave Bird vs. 252 HP / 252+ Def Sableye: 163-193 (53.6 - 63.4%) -- guaranteed 2HKO after Leftovers recovery
This may seem bad, but you burn it and force it into this:
252 Atk burned Braviary Brave Bird vs. 252 HP / 252+ Def Sableye: 81-96 (26.6 - 31.5%) -- 26% chance to 4HKO after Leftovers recovery
This is not a 2hko even if you get max rolls. You're free to spam Recovers, and even Knock off its Scarf if you want, since it's not doing much against you after being burnt.
