Looking at your current build, it feels like it has low damage and no way to remove debuffs. Danzo and Iruka don't do much damage themselves.
That said, here's my suggestion:
Mei, Fire Main, GNW TenTen, Sailor Sakura
4, 4, 3, 4, 2 Lightning Tiger
(Lightning Tiger for max combos. However, Mei's mystery will not get immobile, so you might change the chases to lower the number of combos and but instead give you Mei's chase on Mei's mystery).
Activate Fire Main's mystery round 1. Bani Chakra activates twice turn 1, giving you the 60 chakra needed for GNW Tenten.
Tank the enemy damage on Round 2. Use Sailor Sakura to clear any debuffs and heal. Then Bani Chara will give you the 20 chakra needed for Mei mystery.
Repeat TenTen and Mei mysteries until your opponent is hopefully dead. Hope this helps.
