An un-rules ruling(s) that came up in a game I really played recently. I have Another Aether Vortex. My opponent's library's top card is an Augment creature. There's a host on their battlefield. A. Can the augment attack since it kind of has stats? B. What if anything happens with the augment's abilities? C. Can it augment the host?

Augment cards function similar to auras. If they are somehow on the battlefield, but not attached to another permanent, they are destroyed by state based effects and go to the graveyard. If you have Yet Another Aether Vortex, you’ll get your turn over the top card of your library and if it’s a permanent, it will also be on the battlefield. And no, it will be too late to augment it to a host.

Why does power level have to be at a constant level for this hypothetical product though? If its entirely reprints and doesn't introduce new cards to formats, and doesn't have a limited format, why cant it be super over the top power level? If there was a booster product that was entirely bomb rare and mythic reprints, and priced at normal booster prices, wouldn't it be the best selling product wotc has ever made?

Okay, one last one and I swear I’ll stop talking about this.All booster packs at the same price have to be the same power level (roughly) or the higher power one will sell and the rest won’t. Our goal isn’t to make only one product the players want to buy.

Wait Mark. Ron Spencer is my favorite MTG artist ever, and I don’t know how to thank you for bringing back the Infernal Spawn family (and his unique style)!!! I’m so excited about Unsanctioned, but this pushes it over the top!

I was excited that we could make it happen. It’s one of the things I was bummed didn’t make it into Unstable.

With regards to "X planet" qualities, you say that you don't want players to have no idea what to expect. I don't think that's very true; I think that you're trapping yourself into assuming that players want recognizable features of a plane when really they just respond to quality.

Let’s say we made Fornavia which was Kaladesh, Amonkhet and Ixalan combined with each being a separate continent. Does that make the game better? Does that make the plane better? When we say Return to Fornavia, are you excited? You don’t know what it means. I’m just pointing out that identification of worlds is more important than a sense of individual world depth, because we want to create a connection between game play and world flavor. The depth is in the multiverse, not the individual planes. The biggest problem we’re having with Dominaria (and in general the reception has been over the top positive) is that players expected some attribute they loved of the world and we simply didn’t have enough space to fit it all in.

What's non-blacboardable about Mine, Mine Mine! ? Just the potential for a combo breaking formats?

It’s an example of something that in the day was over the top but since has become something black border is just willing to do.

When designing Kaladesh, did you keep in mind that modern affinity is a thing and avoid creating cards that would put that deck even further over the top?

Modern doesn’t dictate what we can or cannot print. If it causes a problem, Modern has a banned list to address it.

Does the existence of modern ever stop something from being reprinted in standard? For instance, I doubt Invigorate would be all that great in standard but it might push modern infect over the top.

It’s something development thinks about but if it was something Standard really needed, I think development would use it and then see if it truly causes a problem in Modern. If it did, there are ways to address it.

Some of the comments about the legend rule are Insane. I think it will be a good change for the game. I understand people being upset but some of these comments are way over the top.

Magic is something people are very passionate about and when you make changes to something people care very deeply about, you are going to get some very strong and emotional reactions.

I think a lot of people (self included) just don't like Jace the character. Being a brooding badass makes him kind of obnoxious and one-dimensional. That one-dimensionality is grating when he's made the public face of Magic. To give a really over the top example, imagine if Magic was represented by Poochy, the Rockin' Dog from the Simpsons. People resent that kind of stuff because it suggests marketing has a low opinion of them.

I would suggest reading some of the novels, comics, etc. Jace is a multi-faceted layered character. As a guy who studied writing, he’s one of the characters I would most like to use if I were writing Magic stories. Also, he’s the most popular according to our market research.
