If you want to have fun knowing that very likely you will never be able to compete for top positions, yes he is the best ninja you can get,overall if you give him assist links mystery.

Otherwise go for agk or naruto six paths.

If all the people like him quitted you would have none to plunder. Instead of being grateful there are people that like to play even if they know they'll never be top10 you ask them to quit LOL. Very wise.

For kushimaru jinpachi mb they usually run onoki, gaara kk or edo sasori as the 4th ninja.

Jonin minato iruka kurenai wind main is quite solid for early and mid-tier game play.

Jonin minato with bonds, together with kurenai full sb and han (until you get madara 5ks) is also a decent shark bomb team.

The most efficient shisui team you may run, with the lowest expense, is shisui iruka itachi anbu fire/lightning main. Where you replace iruka with madara founder if you get him as 1st super rare in gnw treasure.
