im also interested, i got him from pain treasure and am looking, maybe neji to start

yamato is very good on ninetail his barrier really usefull

As a ninja he is most useful for earth main, considering his barrier buffs earth. I wouldn't see him being used in a lightning main team, apart from possibly ninetails, in which there are also better options out there.

i have a good team with him
