Sup guys, so I'm gonna be getting X on Monday and since I've gotten older I've gotten to the point where i lose interest in the games pretty quick (last two gens i beat the story line with basically my starter and that was it) so to try and keep myself interested I'm gonna try to get into the competitive scene, which I've never done before. So I've thought of something to make it kinda interesting: Post one of your Pokebros thats part of your serious team and give me it's set up, nature and "role" in your team.

Also general tips for a beginner would be thankful as well

TL;DR Post one of your favorite pokemon for competitive and its set up
