Also I forgot to add, Pretty interesting team yourself. Personally I phased Tobi out before they end up nerfing him other wise I would probably have him in instead of Tsunade.
If tobi does eventually get nerfed, who should replace him?
Well that is really subjective towards the team you are building. Personally I replaced him with Tsunade because of her self heal using her as my side tank instead.
He could also be replaced with another tank or perhaps GNW konkuro if you want the ignite.
