Hi, welcome to Smogon! I'll have to lock this for the time being as the RMT rules require that you provide in-depth descriptions for each Pokemon to explain your choices and their roles. Please read the rules carefully and take a look at other RMTs and the RMT archive to see the kind of detail and format we require. PM me with updated descriptions and I'll be happy to unlock this.
