I've found that if you're going for a team that can combo over 10, a good team is: Main (Lightning obviously), Hinata, Sasuke, and Kabuto, with Kabuto and Sasuke usually behind the first two. One of the more noticeable flaws however, is that Kabuto cant normally attack, just only from combos and clones (kinda unfair since Naruto 3 Star spams clones each round), however, he can take care of debuffs for up to 2 members, heal a decent amount, and provide assistance if he's able to set up his clones.

Haha, thanks for a reply, I wasnt struggling much in Matsuri, got lucky to not get any top server dudes, anyway I went with Guy - Hinata - Sasuke, lost with it first round but I sweeped rest with naruto - neji(gnw) - kakashi it wasnt very good though. And tried the last one with Tsunade - Kakuzu - Tobi, it was little slow but I managed to defeat with it Kurenai - Hinata - Tobi - Earth with similiar power.
