You have black 2 right? Why dont you level up your pokemon with the dojo shop in the join avenue? Or you can get the cafe shop?In the cafe shop, at rank ten, you can level up your pokemon by 13 levels, and in the dojo, you can level up by 10. So in total its 23 levels each day. On the subject of the battle institute, I tried it first before I knew about ev training and kind of a noob, and I got SLAUGHTERED!
