After one have beaten Elite Four, and fought pretty much all trainers in the game, how do one train one's Pokemons most effective?
I have tried battling Elite Four again, and even though that seems to be the obvious answer, it is pretty boring, after all ^^
I have tried the Battle Chateau, but all the trainers seems to be underleveled (I started battling them efter the Elite Four, so it may just be because I haven't beaten them enough).
The last option is the wild Pokemon at the end of Victory Road, but that seems like the slowest option.
So, what seems to be the right answer? In Black/White there was the stadions with roughly level 60 Pokemons, I am in search of something like that :)
