I ended up having to ditch my Loudred because he would just faint in every battle and was horrible, it was a tough choice because he's also my rock smasher.
I also have Latios in my 6th slot currently as I decided to teach him Surf until I can obtain someone who I'd like to teach it to (I dunno why but I really don't wanna give it to Michonne).
Also, as you can see my Altaria is still unnamed. I often wait a while before naming my Pokemon to see if anything comes to mind on my journey, but nothing has, so feel free to PM me suggestions.
