Hey, good team. I have to say only one thing, what do you do against the dragons opponents? Yeah, you can revengekill their easily, but you haven't switch in vs dragons pokemon, so forretress > donphan can be a good idea. (sdefenser set imo will work well in your team)
Ah, use ice beam > blizzard on your kyurem, it has more pp (good for stall oppo) and it has maximum precision in the rain, sun and sand.
