I was wondering if there is a poke in rotation that attacks and then switches with bench like ferrothorn

To answer your question, there are two cards that do what you're talking about. Forretress UD and Palkia CL both switch themselves and the Defending Pokemon while doing damage. If you are looking for cards that switch only your Pokemon (or only your opponents), then please ask that in the link I provided.
