Sensei Postcard

If you log on to Club Penguin you would recieve a postcard from the grat card jitsu master, Sensei, but if you already got it and you log on to see it again to bad you wont see it. It says he is visiting July 3 - 5 and you have to be a ninja to meet him and so on BUT it says he will teach you a new move? What will it be? Is it going to be some new card for card jitsu? Maybe its a backgroud? We will tell you as soon as possible. His white puffle stamp is cool.
