I think cloyster should move up because its shell smash set can be a devstating sweep if it sets up. Its solid defense can also set up spikes against certain variants of lando and garchomp. Rimbombee is a great set up mon with light screen reflect and sticky web and what makes it diffrent its amazing speed stat. It gives great speed control. Also garydos can be devistating wall breaker with dragon dance moxie sweep.
