Is there a specific reason why more auras or equipment like Dub and Captain's Hook don't change creature classes? There are axes that react to warriors entering the battlefield or using them, but no specific effect to BECOME a Warrior. And most "general" type change effects are Blue (Arcane Adaptations, Xenograft, etc), limiting use outside of Blue.

It’s mostly a memory issue. If we do it too much, it becomes harder to track.

"We’ve moved away from what we dub “gimmick sets”. " even as supplemental sets?

Yes. They are hard to make and don’t play as well.

Hello Mark, where would you put an all creature set (like Legions) on the storm scale?

A 10. We’ve moved away from what we dub “gimmick sets”.

I also feel the need to point out the difference between people who enjoy [mixing sci-fi and fantasy] and people who are indifferent to it, but enjoy the cards *mechanically* and will buy them simply because they are good cards. I sincerely do hope that WotC acknowledges that a set selling well doesn't automatically mean that it was well-received. I feel that Kamigawa NEO is well-designed mechanically but dislike the modern-day and sci-fi technology aspects of the flavour.

If a set sells well, and does well in market research, and gets played a lot by all the metrics we can measure, and gets talked about a lot through the many metrics we can measure, we dub that a success. We understand that not every product is optimized for every player, and there are things that some players love that other players are neutral about (and yet others hate), but when something does well in all our metrics, we assume there’s a significant portion of that audience that enjoyed what we made.
