Pokémon Black and White 2

I only know one instance of such a trainer along the route to Join Avenue. I remember her saying that she'll battle you every time you pass by the area, so it's probably not a glitch.

Either way, Amulet Coin the heck out of them.

But it has happened with three different trainers, all of them female pkmn breeders. My friend also suggested used adn amulet coin to farm for poke but they dont give much anyways.

Edit: Oh... i did not realize breeders rebattle you... never happened in earlier games. I have not seen too many male breeders either so i guess i just did not notice
