A cube is basically a limited format where you make your own set and so on and then draft it. (Tons of replay value and oodles of fun! etc.) Patrick Sullivan is a decently well-known Red mage in the tournament scene - and friend of Mike Flores. As for tournaments, I am really happy to see so many cool cards in the tournament scene right now being used from the RTR block (things like Sphinx's Revelation is being played in ... 4-color midrange?!).
