Try with your 9 tails team, worked for me, just killed him on turn 3 before he killed me, didn't bother with interrupts.

So what do you use to kill 9 tails lol, it means team that does high damage with normal attacks, not combos. Something like Jirobo/Guy/Kiba, or just look in this section for other threads if you want more options, this is asked a lot.
