Did not see a team rating thread, can we have one?

This is what I wound up beating the elite 4 with, and it seems lacking.

Given Toxapex, I know I probably should get rid of my milotic, and replace my leafeon and dugtrio with something else, but I don't really know what to do. I really should have at least one fire move I feel, but I have never done any competitive battling before this gen.
