Hmm...I actually have an extra team I made on Platinum with half of the Pokemon available!
These are the ones I definitely want to try to use:
White Kyurem (gotta have my Legendary!)
Those are from the confirmed list. I was originally thinking of using Serperior, but if I can try to make a better version of that team I made before, I just may sub out my starter this time. Gotta wait to see which other Pokemon will appear though.
