Hi, 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.
