pitiful stanima?don't underestimate kakashi,he know very well about tsunade's abilitty.kakashi has a good stanima 3 just like hiruzen,if you look at pein's fight he was able to do1. Yes, she can keep up with Kakashi, maybe not the entire match but for the time she needs to execute her plan she can. Also Kakashi can't run for the whole match either, he can probably outrun Tsunade for a couple of minutes due to his pitiful stamina. This also alters how many strong attacks he can perform later in the battle.
2. Yes, she is reputed for her fighting skills and monster strength. (Taijutsu)
3. Her "healing techniques"..as degrading as that sounds, involve the Creation Rebirth which takes only a few seconds to activate. This provides constant recreation of cells and organs and also provides an immense amount of chajra for the user to do whatever she wants (Yin Seal: Release).
4. If Tsunade, for some reason, let's Kakashi in close range (where she has the advantage) and also gives him the time to perform a Kamui..she can still recover almost instantly. This is assuming she stands still like an idiot and doesn't try to evade it after he performs it. This is situation is very unlikely, because all she needs is one good punch or one of her electrical waves to reach Kakashi (immediately paralyzing him). Even if this unlikely scenario takes place, she can still recover and keep battling while Kakashi is wasting chakra and stamina.
Tsunade has more chances of winning.
4 raikiri
1 doton
1 lighting beast
and said that tooks 50% of his chakra,then he did
1 more raikiri
1 more doton
2 kamui
and since kakashi seems to get used with his sharingan,it seems that the sharingan got less influence than before on his body since first part.
tsunade is late she can make any plan she want ,she can't touch kakashi who got sahringan and is by far fastest than her
.and no in close middle range,kakashi got advantage , if you look at last time kakashi used kamui,it was against tobi at close range,he was ready to send him in an other dimension until tobi said that it doesn't affect him.
if she don't have high genjutsu skills,high speed or tobi's ability ,there is no way for her to dodge kamui in close range.you talk about kamui like if it's a late jutsu... you do not realize it's instant hit ,the moment tsunade would come at close fight kakashi just has to activate kamui in a fraction of second just like the susanoo arrow that is big like 3 human.
notice that kakashi never missed to aim the target unless vs deidara but he said himself that he had problem to control location and the barrier limiting area and still he his arm and solved this problem vs pein and sasuke's arrow.
kakashi win this.
