First of all, if you really want to be a serious OU player, then change "UU Player" in your signature to "OU Player". How far do you think you're going to get in OU if you endorse yourself as a UU Player?
Secondly, use a Landorus-T. Those are good.
Third, make sure all of your Pokémon are holding items. If they are, it'll give you a big advantage!
Finally, I'd recommend winning more games than you lose. If you do this, then you should be a pretty good player!
Haha, seriously though, I'd recommend the following:
- Being a good Pokémon player means having both good teambuilding skills and good plays. Read the Teambuilding Guide if you haven't already.
- Watch replays of high level players, and look at the plays they make. A good place to check out is the OUPL II Replays thread. Try taking a look at their teams as well. Figuring out why they used the Pokémon they did is a good way to make you a better player.
- Get your team rated here! The RMT subforum is helpful because it lets other people look at your team, and in teambuilding, two heads are better than one. By using the knowledge you already have, you can also help out less skilled players.
