Firstly add some sort or description of the team, second don't run to mega stones on a team, because each game you have at least 1 not that useful teamate. I think this team is Ubers because of the Mega Mence (mega mence isn't allowed in OU, youre team gets destroyed by common uber pokemon. Change your pfp too lol

Welcome to Smogon! I'm locking your RMT for the time being as the forum rules require that you provide at least 3 lines of descriptions for each Pokemon to explain their roles. Please read the rules carefully and take a look at Team Showcase to see the level of detail we require. PM me with updated descriptions and I'll be happy to unlock this.
