Is my pokemon team good?

You have a pretty well balanced team. It depends on which pokemon game you're talking about, though. It might be better if you let your staraptor learn brave bird (which it learns at around level 49). Apart from that, and depending on your place in the story, it seems a pretty good team. Have you just got the riolu? Just wondered why it was a lower level. If you get that trained up to around 40 with your other pokemon (exp. share or just normal battles), it would be a great help in battles =D
