Answer 1

Okay first let's start with your platinum team. Get back the signiture moves for Giratina (Shadow Force), Dialga (Roar of Time), and Palkia (Spacial Rend). Also it seems to me that you like the move thunder. It's a decent move on its own but try teaching one of the pokemon that knows thunder the move rain dance which would greatly improve thunder's accuracy. Palkia would be the best candidate for that combo. A final bit of advice for this team would be to try for more pokemon-/move-type agreement.

Now for your Black version team. Simipour needs some more water-type moves, a good suggestion would be Scald (TM 55). Serperior and Sigilyph are fine, but Sawk could use either Bide or Reversal in place of Payback.

A last piece of advice overall would be to give everyone an item that would increase the power of the pokemon's moves. Hope this helps.
