The other day I decided I would finally beat the Battle Frontier. Ever since I've had Emerald, I've been its bitch. So I'm now on a mission to completely take the Battle Frontier. I'm currently in the process of getting my first symbol.
Has anyone else completely taken the Battle Frontier? Or at least won a few symbols?
P.S I also find it ridiculous that we can't use legendaries, but almost every Frontier Brain uses them.
