I want to try BW NU, and I've already tried RU and UU. I really like those two tiers, much better than BW OU!
I'm trying to get as many points in the DW as possible so I can get some of the better DW mons. Specifically, Tauros, Poliwag, Vulpix, and Bagon :p So far I have ~7000 points. Playing all the mini games really helps... I used to just skip the games if the Pokemon they were for were useless .-.
I would like to try DPP LC, but I never have. I want to try to get back into WiFi battling but it takes me a while to build a good team online, and then I have to RNG the team and EV it. It takes a while :p
