So I have see most threads are about Team Building Helps. I may not be the best competitive battler in the Pokemon World, but I knew a lot of how to be the sweeper.
Tell me which "Weather" you are going to use. Either none, Sandstorm, Hail, etc.
Then tell me what would you be thinking to do. I might only rate it and try to tell you more how to improve, or I would say that it is good enough.
In Conclusion, Ask me. You can test your team by battling me.
