I beat the elite four and beat N and trained for a while but the Pokemon I had weren't the ones I wanted and were underleveled/terrible. I started a new file and am wondering what to catch. So far I'm going to get these: Oshawatt, Pansear (might not keep him), Axew, and Sawk. (This is on my Pokemon Black version)

i beat the elite four with samurott, krookodile, victini, fraxure, emolga and a watchog. however, i got rid of watchog in order to get reshiram. you might not be able to get victini, obviously.
