Being new to the game its hard to pump out a pro comp team with the resources you have, so I suggest sticking with pokemon you are keen too, use them in comp until you get to a point where you can understand and identify problems and solutions your team needs for that meta. By the time you get to that point (and a bit before) you can look into comp teams that practice on a regular basis to help you expand your knowledge even more, and have more resources available to you to reach that next level of comp play you want to achieve. I know it seems like a bit of work, but that's kinda the point of PokeMMO, and when you reach to the end of that work and get to that level I know it will be really rewarding to you! :D
