I think so. You're welcome. ^_^ It was fun.
I have 472 pokemon in my Platinum dex. I have 3 stars on my trainer card.
In order for it to be complete:
No Kanto pokes needed.
For Johto, Raikou, Entei, Suicune, Pupitar (Have Larvitar), Lugia, Ho-oh, Celebi.
For Hoenn, Slaking (Have Vigoroth), Numel (Emerald), Solrock (Emerald), Baltoy (Emerald), Almaldo (have Anorith), Wynaut (in Emerald), Metang (Have Beldum), Latias, Latios, Kyogre (could get in Emerald later on), Jirachi, Deoxys.
For Sinnoh, Regigigas and Cresselia. I'm going to try to get Regigigas by getting the three Regis in Emerald.
