I heard a lot of people saying they had trouble with Sasori, so I was a little nervous going in, but I just fought him with no problem. My team:

fire main Kakashi x
x x x
Kabuto Kiba (Ninja War) x

and my summon, little Katsuyu. I killed him with combos, haha. More specifically, I targeted Sasori when he had no puppets, but the puppets as soon as he created them.
