Exactly, I can count the OU Bugs on one hand while the rest are in UU/NU/RU. And the only one absolutely good Bug I could use is banned to Ubers.
I'm starting to notice things lately.
One of them isn't so much that a type has an issue with Mono-Gym
But your battle style (Single, Doubles, Triples, Rotation) can make or break a type.
Maybe a Doubles bug team?
Volcarona has access to Rage Powder and Hurricane (Rain).
I'm sure there's a bug with Wide Guard for Rock Slide.
You also get the benefit of speed control because of Sticky Web and Tailwind.
You could utilize Galvantula and another Bug type for a small Volt Turn Core.
Quick Guard could help you deal with pesky Talonflame if you have a teammate ready to KO it after Quick Guard blocks Brave Bird.
