Since I'm getting close to Six Paths Sennin, I've decided to post my lineup. This lineup works in sage battles as well. I'm sure people might already know about this lineup.
Edit: I forgot about my summon. I use the shark/flood dragon.
Round One: Use Hinata's mystery.
Round Two: Decide whether to use Kankuro or Main's mystery. If your Kankuro puppet is dead, I would use my Main's mystery. Having more initiative is key. If I'm against a fire main, I would wait until he/she uses their mystery until I decide on what to cast.
Round Three: Usually the match would be decided already. I just use whatever I didn't use last round.
The match is still winnable if your main dies. The key factor to your victory is Kankuro since his mystery with clone alive does so much damage.
I hope you have learned something from this and thanks for reading my first guide :)
