Nicely done ^^ I could do a topic for my monotype, but the amount of laziness is too damn high... Anyway, i guess the recommendation i can give you: Don't keep that Whismur for long, unless you have pacience for Exploud, cuz that thing will be dying (Change for Wigglytuff in the future maybe? Idk...)
Good luck, hopefully all your pokemon are going to have bad natures and bad IV in the future
EDIT: Whismur's Rattled turns into Scrappy right? Hmm... maybe you should keep whismur around for Shade, unless you have a better idea...
