Mr. Trousers, it might be humourous to note that I primarily do Dark Horse shenanigans whenever I do anything related to OU. Part of this is to be creative and use stuff that people might not necessarily see as good at a first glance (I actually toyed with OU using Swords Dance Meganium, and I'm willing to do it again just for fun). That said, I will be of some service in regards to Stoutland and Hippowdon, as I also plan to use them. However, I will not stand in your way in terms of the Project, due to my hesitation regarding alts. I have one alt, /D/usknoir, who was created because of the downloaded PS! app not having the same teambuilding cookies as my usual teambuilding.
Example: This is a battle where Roserade ended up being awesome, as an example of the kind of teams I'd employ for the specific Pokemon.
