Interesting to see a Metagross, but you must have at least 3 lines of information for each Pokemon (This is better to understand what your team wants to accomplish and what your thoughts were while building it).
If you don't do this, the thread will be closed.

Hey SammyP! It is required that you have a minimum of three lines of description for each Pokemon to explain your choices and their roles as outlined by the RMT rules. Please read them carefully and take a look at other RMTs and the RMT archive to see the kind of detail we require before posting a thread here. PM me with an updated version of your RMT after you review the rules and I'll reopen this thread.
