Rate my diamond team and give suggestions?

ok your team is really good i would suggest that you add in some moves like bulk up/calm mind/swords dance/or whatever works just for some added help in battles for staraptor i dould suggest something like roost to restore hp if needed or u-turn for a psychic killer atk or feather dance if you are needing to reduce opponents atk those are three moves i would choose from lol but i give your team a 10/10 so good luck
