I use him only for 9-tail. Hashirama Iruka WB asuma and fire main, 1m+ dmg per run.

hashirama in the middle row, the other 3 in the back.
talent is 2 2 1 3 1 i think. (dragon flame, high combo normal attack, chase 10 combo, fire enchant, clone)
summon tonton

round 1 hashirama ult, iruka ult
round 2 main ult
round 3 main ult
round 4 hashirama, iruka, WB asuma ult
And yes you can auto. Just make sure to put asuma in first, then fire main ,then the rest. In this way your fire main will ult at 2nd and 3rd round.

This is the best 9-tail formation IMO.
