Hebi Sasuke takes this mid diff, Kakashi doesn't stand a chance.
-CQC is suicide due to Chidori Katana and Nagashi. (We all saw what happened to Yamato)
-Sasuke dominates in long range due to his Fire Style and Chidori variants.
-He has Curse Mark levels 1 and 2.
-Can summon Manda. (Though he needs to control him via Sharingan)
Again, Kakashi doesn't stand a chance.
kakashi is lighting's user too and he has zabuza sword and can put raiki in it
kakashi's raiki is advanced chidori ,so kakashi's light can beat sasuke's light ,kakashi's raiki beats sasuke's chidori nagashi
kakashi can counter the fire by water and he can counter fire and chidori variants by going underground or avoids it
kakashi can counter kirin by his lighting jutsu ,he was able before to cut lighting storm by his raiki
kakashi can kill manda by raiki chain or raiki's shurukin
if kakashi can perform zabuza's mist ,he will surly win
i think yes he can use it ,kakashi saw its hand signs several times, we all know that kakashi is the copier ninja,kakashi copied all zabuza's water jutsus ,and he used the mist against itachi in the anime ,but it still logical thing
3 tome sharingan kakashi has great chance to beat him and hebi sasuke too
