I would usually say Chojuro breaktrough, but you don't have him 4 Stars yet. Especially with Suigetsu team Taka, he could be quite devastating. Also does he work perfectly together with both Lighting main and Water main, so I would definitly recomend to get him 4 stars, even though 3 stars might be enough right now.

I mean, you could go for the overly standart Kimimaro/lighting main/Jugo/Sasuke comp, but as far as I can tell, a sword/kiri team together with Suigetsu should be relatively strong, and for some reason Team Taka Suigetsu also shields kiri-nin, even though it should only be Akatsuki members.
