Where can I train Pokemon at lv 90 in Pokemon black 2?

Question

I have a lv 90ish raichu and I wanna train it to lv 100. Do any of you guys know a good place to train it besides the Elite 4 place?

Answer 1

You could try training at the Black Tower, on the tenth floor they have very high leveled Pokemon.

Hope I helped!
