Regarding his biggest fear and Magic's biggest threats:

“The places I get worried about are Magic’s tournament system, which has historically been important to Magic’s health. And then the philosophy that you should not make rare cards so powerful that you need them. People feel that’s a philosophy that has been broken from time to time, and I think it’s always been a mistake. It might have made money in the short run, but it has hurt the game in the long run, or at least until it was corrected,” he said.

“I think things that are existential threats for a game like Magic is if the community breaks down, and here I'm thinking of the community built around tournaments, but not just that. Or if people see it as being a game where you can buy victory, which is associated with this idea of making rare cards too powerful—or powerful cards too rare would be another way to put it. Those are serious problems which might lead to short-term profit but will lead to long-term problems that could be catastrophic.”
