So I'm doing a Nuzlocke and I'm in a bit of a predicament. The Blackthorn City's Gym Leader Clair probably has lvl 35-40 Pokémon while mine are stuck down at 31-33. Is there any good place to train for the Gym other than the Gym itself?
I'm don't really want to spend 2+ hours grinding, so speed is of the essence. My team consists of Nidoking, Togetic, Growlithe, Gyarados, Kingler, and Ampharos.
