A somewhat troll set ;D
Galvantula @ Binding Band
Ability: Compound Eyes
EVs: 6 HP / 252 SpA / 252 Spe
Modest Nature
- Infestation
- Electroweb
- Hidden Power [Water] / Hidden Power [Ground]
- Gastro Acid
I know, these aren't the strongest moves, but at least you can annoy your opponent and bleed his/her pokémon to death. Trap yout enemies with Infestation in the first round (powered up by Binding Band), then take out their ability with Gastro Acid, then finish them with Electroweb attacks, increasing its accuracy with Compund Eyes! Hidden Power covers Fire and Rock weaknesses, and of course, Ground covers more types, but Water type is not the end of the world, I guess. :D
