Due to the rumors of Chespin's final evolution being a grass/dark Pokemon and the recent amount of pretty good looking dark types such as Pangoro, Malamar, and Yveltal being revealed I've been considering using a party of all dark type Pokemon upon the release of X/Y. I know anything that knows moves like Mach Punch or a speedy bug will flip my shit, but it seems like it would be fun to just use one type for a game. Any thoughts?
