meh its offical, skymin won't be banned
and woo, a team consisiting of wobby, garchomp, deoxy-s and skymin... what fun... not.
None of those Pokemon with the possible exception of Shaymin-s (who is untested) are broken, and they have poor synergy anyway. I doubt your "team" proposed would even do well; I think the refrigerator Rotom makes all four of them sweat actually.
We don't have data about a lot of unevolved Pokemon so we didn't include them. They will be added, along with sprites for the new Pokemon, shortly. Platinum sprites for Pokemon with DP sprites are extremely low priority; it seriously doesn't matter at all.
Hypnosis's accuracy reduction was good design in my opinion; it fixes the original mistake DP had of hurting the special utility of grass types for sleep. The way it stands now, Sleep Powder is again much more accurate than Hypnosis; that seems more fair to me than it being just barely more accurate. In any case, we have to move forward. Platinum made the mechanics change, and Platinum will be the standard. Shoddy Battle's only job here is to faithfully emulate the game mechanic.
If you don't see Pokemon with new moves, make a new team. Opening an old team can cause problems. If you still don't see them, I'm not sure what your problem could be; be sure you are checking a fully evolved Pokemon that has at least one new move (so not Wobbuffet, Ditto, or Unown).
