You just need edo deidara to complete the deidara - sharkisame - jimpachi team. If i was you, i would try to get him as fast as possible.

Anyway, you have a good amount of ninjas, but you are lacking both GNW supers and itachi susano'o, probably the most common ninjas in the "whale tier".

Edit: i totally forgot. Probably, the best team you could build would be a root LM, black hidan, hairy kakuzu and either a buffer (konan, mifune), a fire barrier ninja (onoki, my fav choice) or even a random sharkisame in 3rd position.

LM, Hidan Death, Roshi, Killer Bee
