Firstly, congrats on the sosp. About the advice you're asking, it depends on what you're looking for. If you are at a good position to get fast win streaks in your current SWB arena in power level let's say, you may consider some WB Asuma + Ohnoki/KK Gaara for him in order to get t1 sosp or t1 double hit followed by a finisher t2.

If you are looking for more of a control/consistency team: Kurenai, Chiriku, Gakido Pain, Gaara [Shippuden] and Orochimaru [Akatsuki] might be your support character pool that you'd want to consider.
