BM Minato and Tobirama win this low/mid diff at most
--BM Minato can powerup TObirama as the latter can use his GKFx3 through his edos, (that are tagged by him) thus annihilating all variants of itachis susanoo, and allowing them to finish itachi off
--nagato being edo means that he lacks the mobility, not to mention that he doesnt stand much of a chance against minatos firepower, as TBB barrages synced with FTG just make it easier for minato to finish him off, not to mention that goshun mawashi can also be used to finish nagato off
--Minatos kurama avatar durability also allows him to tank pretty much all of his attacks, and with tobirama also assisting him through his GKF, they make quick work out of nagato,
--Restricting GM for nagato, and the fact that tobirama has 3 edos, whilst minato can power him up, and fire off TBB barrages to wreck both of them, means that the akatsukis dont stand a chance
