Hi there! I'll have to lock this as you are lacking descriptions for the choice of your Pokemon that is required by the RMT rules. You need to provide in-depth descriptions(preferably at least 3 lines) for each Pokemon to explain your choices and their roles in the team. 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. You can PM me the updated version of the RMT that complies with the rules and I'll be happy to unlock it for you. Have a nice day
