Normally, as our crazy bus trip progresses, we’ll be posting notices of our guests about an hour before they join our broadcast. However, because I expect a lot of activity on the blog in the first couple hours of the event, I’m posting our first guest a little early. Those of you who watched this week’s installment of LoadingReadyRun will know that we all recently became very very re-addicted to Magic: The Gathering, so we couldn’t be happier to welcome Mark Rosewater, the lead designer for Magic at Wizards of the Coast, who will be calling in to speak with us at around 7:00pm PST!

Mark has headed up Magic development over the course of many expansion blocks, and has comedy writing chops from years of working in television. He’s famous for his love of crazy mechanics, and his proclivity for writing extremely long blog posts about design, life, and the funny place where the two connect. We’re hoping that chatting with him will ease the pangs of addiction  from missing Friday Night Magic–only one of the many trials to be suffered as the crew embarks on the first leg of its journey.

Wizards of the Coast has also donated a pretty astonishing selection of prizes–sure to tune your Elder Dragon Highlander deck into  something absolutely terrifying–so stay tuned as those are auctioned off later in the event!

If you have any questions for Mark, you can post them here: we don’t promise to ask him everything (or anything) that’s posted, but we may draw on your questions if we have time.
