This team is not viable for pvp because 1st hokage in 4th spot with non prompt mystery will most likely get interrupted, your main might gets too much damage being in front line or maybe get controlled after tsunade standard heals, tobirama blindness is not good against immune and healer teams or mirror teams which may reflect back to you, 2nd round you will have 40 chakra, if you are lucky you c*e water main else you will rely on tsunade to heal or either have to use her mystery then you will left with 20 chakra and round 3 you will have a total of 60 chakra, best case your main will be alive and you c*e her, worst case main dead, you have to use tobirama, where he may get controlled depending on the other team. (This team is luck and raw power based in my opinion.)
