hey there, thanks so much for ur guide!~ really helped me huge time !! (Y)
*some points to note*
1) if tobirama blinds naruto early, its best to reset - because naruto wouldnt be able to combo.
2) in between round 6 & 7 , when u use Shark Bomb on tobirama, IF Zabuza dies, keep going ! just use Rasengan on sarutobi, and let the poison do the work! the final health of hashirama would be quite easy even with auto attacks ( and as long as you have ONE ninja capable of using a mystery on the next turn, you are good !~ )
