Forgive this for being slightly off-topic.

But I've wondered for awhile now, if a MTG-style card game might not be an ideal application for blockchain technology. The anti-counterfeiting concept means that limited numbers of rare (virtual) cards could be issued. A mechanism could surely be developed where the company or group in charge could periodically release new cards (perhaps after the mechanics had been voted on by participants), and issued once or twice a year. And of course, players could transfer cards to each other whenever they liked, either trading them or selling for an agreed upon price.

It just seems like a natural fit. Wonder why no one's doing it.
