I actually wanted to delve into UU, only becuase the Pokemon there looked cooler than the ones in OU (Arcanine, Milotic, Roserade, Mismagius) :D. I tried Little Cup but I just didn't get it... In the end I just decided to stick with OU, seeing as how I didn't want to spend an excessive amount of time on PO.
Also thought of a cool new team :D. Getting quite sick of my sand team (went to #2 and then got haxxed to death, sitting at around 50 now). Its just everywhere and not as fun. Trying out Choice Scarf Jirachi + MixedMence core 8D..
