Club Penguin Card Jitsu Stone Theory

Here is my theory for Club Penguin Stone. When I was waddling around the dojo, I noticed there was a black like stone in the middle of the room. Check it out to see what I mean.

See that black stone? I think it means that we might have another Card Jitsu coming up! This is my theory of the Club Penguin Stone. What do you guys think about the stone? Tell us in the comments!
