the encryption method is weak, the player can recognize x when he used to have that card.

The encryption key of a card should be changed after every time the ownership of its has been transferred.

Another method is changing the encryption key each round, and use SPN instead of XOR.

I don't think it is necessary to re-encrypt everything in each round, since the ownerships of most cards are not change.

And this may cause a problem because the client need a consistent "id" to track the transition state.
