Presumably, the game maker would create a rare "card" and put it on the blockchain, and transfer it to a player in a transaction. That player could then transfer it to some other player, etc. To be used in a game, a player would have to be able to prove that they are the rightful owner. The player would be represented as their private key ("wallet"), and any "card" that is sent to the player would need a chain of signatures that lead back to the creation of the card by the game maker. I think that blockchain would only be able to represent the custody of the "card", the barter would likely have to happen off-chain. ie, you send me $100 or 1mBTC or whatever and I will sign over my card to you...
