i have a combo of 8

say the team

if you want a combo more than 10 use a ninja with jutsu that can activate more then 1 time during the same round for instance: Chikumatsu Chiyo, Pains, etc. the rare ninjas tend to have this.

also golden summons can get you a 10+ combo

if u use Kakashi Sai and Kabuto
or Zabusa Hinata and kakashi u have 10combo or more

Use it.

I can get a 25 hit combination with Kankuro 3 or 2 star, Kiba Great Ninja War, Kakashi, and main which is Scarlet. :D
