Hi William_tetra, welcome to Smogon! I am locking your RMT for the time being as the forum rules require that you provide at least three lines of descriptions for each Pokemon to explain their roles. Please read the rules carefully and look at Team Showcase to see the detail we require. PM me with updated descriptions, and I will be happy to unlock this. Also, feel free to PM me if you need help or have any question. Have a nice day!
