Mark, you've credited Evan Erwin a couple times with inspiring you to join Tumblr, but you're misremembering. It was actually Robby Rothe (@mtgcolorpie) who suggested it, not Evan Erwin.

Multiple people told me to try Tumblr. Robby might have been the one to post publicly on Twitter.

Do you think there will ever be a "non-player" Hall of Fame for Magic? A place where people like Evan Erwin, BDM, Marshall Sutcliffe and R&D can be immortalized for their contributions to the game and the community surrounding it.

I would love to see the Magic Pro Tour Hall of Fame turn into the Magic Hall of Fame in which the Pro Tour is one wing. There are lots of other people who have contributed to the game other than pro players.

During their set review of the black cards in Modern Masters, Brad Nelson and Evan Erwin got pretty heated about the new art for Dark Confidant. Noting that it seemed like a low blow to have him write an article to tell the public that he's okay with it. While you've already mentioned that there was never any promise to the winners that the art wouldn't be changed, most people seem to believe that it goes against the spirit of the prize. What are your thoughts on this?

While I’m sympathetic to the Invitational winners, here’s the problem. We want to be able to reprint these cards. If they’re in an expert expansion, they have to get new art. That art has to fit the new world. Often that would mean we are unable to have the winner appear again in the art.  It feels wrong to sometimes reuse the invitational winner and sometimes not, so it we made the call that the first appearance of the card is the winner and later reprints are not. (Note we did one promo version with new art for Kai Budde’s card because we felt the original had not turned out as well as we had hoped.) As for Bob, we talked to him and asked him if he wanted to write the article showing off the preview of the new Dark Confidant. Bob was under no obligation to write the article or say anything that he did. He did it because he wanted to not because we forced him to. 

Did you guys forget to spoil the rest of realms before it goes on sale? If not can you tell us when we see the rest?

Evan Erwin did a video where he unboxes the entire set.  You can check it out here: http://www.youtube.com/watch?v=B-ql42F42bY

Are there innistrad cards you prefer the play testing names over what they were released with?

The vast majority of my time with the cards is with the playtest name so I get used to that name.That’s why, for example, I’m so bad at remembering card names (most recently seen in Evan Erwin’s interview with me.) http://www.starcitygames.com/magic/standard/23188_Worlds_2011_Interview_Mark_Rosewater.html Usually when the card gets a real name, I eventually learn to use that name, but sometimes I’m so fond of the playtest name that the new name never sticks. For example, I doubt I will ever call the card Clone Shell because it will always be Meat Puppet to me. Likewise Trepanation Blade will always be Chainsaw.
