Deidara - Sasuke - puppet
***x - GNW Kankuro - main
***x - ***x - ***x
Easy to ignite whole enemy team. 3x double ignite and 2x single ignite on 1st turn.
Kankuro puppet attack (2x ignite) start combo (easy to hit over 10 hits, thanks sasuke), sasuke 10 hit chase another 2x, Deidara 10 hit chase last 2x (plus bonus to nin), Deidara attack 1x ignite after that another 1x ignite before his mystery. It doesn't K.O. but deals a lot dmg, usually it's around 1/2 hp (tested on arena).
Puppet usually dies in 2nd or end of 1st round. Resummon it at the beginning of 3rd turn (to apply as much ignite as you can).
On the middle usually fire mains have hinata so she usually is paralysed on 2nd turn(usually it means rip fire main combo).
Biggest con is no healer. But art is explosion. You don't have to win when you can make art.
