woah, you have so many ninja.
1. What's your main character?
2. how far the difference between your initiative with your enemy? we need defeat your enemy MC first, i believe he is a hitter azure type bcause he put MC in first move.
3. I suggest you use lightning as main character and use root of warrior like they said or you c*e fire main.
4. this is line up if you are use lightning as your main :
Ningendo, MC, x
Sasuke, Sage Naruto, x
x, x, x
Talent : 2, 3, 3, 3, 3
Summon : Rhino
At least this line up will give you 9 combo, if you have darui you can replace sage naruto with darui. it much better because darui buff will give you 40% attack and ninjutsu and you'll get 10 combo :lol

better your try use lightning main, and if you have darui replace rhino with serpent it will give you 10 combo. it's enough to control your enemy main char and also you have mirror because you put ningendo.
