What are some interesting teams you play to stay in top 20?

I have lately tried a bounty hunter / chaze squad that's been pretty fun. Boba (L), Dengar, Greedo, and Chaze. Have had some success, but still pretty rough against a EP, zVader, or R1 team. Still toying with some ideas. I get bored with same team, so I'm always trying new things. My normal team is the zVader (L), Boba, GK, FTP, Asajj. That's a fun team to play with too.

Edit: Been thinking about zeta Sidious lately. I've heard that can be a good addition to the zVader team.
