LF All Kinds of things- pokedex help

[Golden Rule]

I am trying to re-complete the Pokedex. However, I don't just every pokemon registered. All I want to find is the best nature, but, I will take more if you want to offer it. I will offer things for better trades. I don't have to much to offer at the moment but, please make realistic offers. I will have better trades the more help I get. Thanks
