Actual Kakashi (with zabuza sword rampage mode) vs Deidera + Hidan + sasori

[darkheart]

Kakashi can only defeat deidara if given a chance to fight alone one on one

 

[NLee]

Kakashi could win if he goes after them in the right order. He'll have to somehow kill Sasori first before he does his Performance of 100 Technique. Then probably Hidan since he'll be coming after him with his scythe. Then Deidara.
