This is an interesting idea, but I can't help but be worried about that Shikamaru being exposed with no one to block him.

But what if you fight another person with a blitz team, who would in theory easily be able to plow through the clone and potentially kill Shikamaru in R1 or R2?

(Not trying to be overly harsh or critical here. I'm just trying to pinpoint weaknesses and help you improve this team.)
