This Itachi cannot receive any damage during the showdown if your opponent does not have any ninjas with the "Sharingan Eye" characteristic in play. He can receive damage during any other phase (including the exchange of jutsu).
Also, if your opponent has a ninja with "Sharingan Eye" in play, then Itachi can receive damage during the showdown.
