Hey guys, first of all, sorry about my english, it's not my native language. So, I've never played any content of Competitive Pokemon, but now in this game, I'm feeling something about it. I was watching some videos and reading some content in the Smogon, and I ended up with this comp, could you guys rate it and give some advices?
