Ok, so for a starter I will pick Chimchar because I like fire types.

So I will need some water type, any suggestions?
I plan to have Starvy because it's awesome bird. I'll probably catch Shinx but replace him with Pichu/Pikachu/Raichu (I'l breed them for volt tackle probably).
I also want Riolu/Lucario (fur-dur) in my team.

So that leaves space for someone, any must-have dragon type or other pokemon?

I'm not 100% about Lucario yet actually.
