I was in the Hoenn region and my pokemon we're low level... So i went to Kanto, I used one of my higher Pokémon as a leash and I started leveling.. I didn't pay attention and accidentally overleveled them (had max lvl 44 and now they're 46.) There's now no way that I can beat the gyms now with the Pokemon I have, so I'm kinda stuck... Is there a way to get my Pokemon back to level 44?
