Lol I just use whatever I want! I don't follow in-game tiers. XD
Yeah, but don't forget that Altaria, who has a pathetic base 70 special attack, is amazing with a Choice Specs. Most of the top players have used and praised it. Vibrava could be in a similar position with a Choice Band.
And I knew it could learn Superpower, but because it lowers its offensive presence and its mediocre bulk, I didn't think it would be a good idea to mention it. :p
