Well, that's all of them! Items and movesets can be changed, but not so drastically that I have to re-breed the Pokémon ​

I will greatly appreciate your feedback!​

 

That's actually not bad, but I've got a ton of Rock and Ground weakness there...
Maybe I'll leave out either Mega Zard or Mega B-ken, but I'm not sure which one...
