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.

I just looked closer at your ninjas. You could also trade out Sailor Sakura for Ao. It turns the team into more of a control build, with less debuff removal. I changes the playstyle a bit compared to the Water Main version, since you are looking for something different.

I totally understand the feeling. I got bored of WM/Tenten myself.

As for a Hanzo build, i've personally thought about an Earth Main, Onoki, Hanzo build. Hanzo has debuff removal which Earth Main lacks. And Hanzo has immbobile which Onoki lacks. So the three work well as a core build. You can then have your choice of a fire, earth or wind ninja for the fourth ninja.

If you are set on Fire Main, then you have Danzo or Mei as your barrier ninja. Personally i like Mei better for her better stats and higher damage. Which would you prefer? Then your 4th ninja would need to match the barrier.

Probably 21231 and Frog to get Onoki's auto to combo.

Earth Main's Mystery and Standard attack can be changed to whatever you want.
If you put Earth Main in the front row, change the last passive from Earth Style Bolder to Steel Body.

Overall, this team looks weak for PvP, so don't expect too much. That said, it might be good for GNW or Ranked as Hanzo clears debuffs on all three friendly teams and Hanzo/Onoki hit a ton of enemy ninjas.
