Not really arbitrary: 64 pages is 4 16-page folios bound together, and the combined page count is similar to other full length 5E books, so I presume it was budgeted that way to maintain the price point.
I don't think summoning is all that important for a MtG setting, since you're using the setting not playing the game. Players in a MtG setting aren't planeswalkers summoning minions to attack another planeswalker, they're the people in the setting living in that world. While I would have liked the colours of magic to come into it a bit more, I still think the current settings we do have were well done reproductions of individual planes and I'd like to see more of them.
An Ice Age era Dominaria book would be awesome. I’d definitely want some stats for Kjeldoran Skyknights
Honestly the whole Dark - Fallen Empires - Ice Age - Alliances - Coldsnap era would be great.
It would be. I especially think a campaign set during fallen empires just as the ice age is about to begin would be an interesting setting, it'd have that sense if impending doom as the world slowly freezes.
I see a few people doing that on reddit which makes me think, why isn't the dnd team tapping more into this resource.
Part of me wonders if they are waiting until after the current Magic plot line plays out to do something, when they settle on a new status quo.
If I ever get to run Curse of Strahd it will be set in Innistrad with an all human adventuring party. The imagery from the art book is so vivid.
Are the published MtG settings available on DM's Guild?
Theros and Strixhaven are, yes. They both have a good amount of support there, too.
"The vampires have captured you."
Not Ravnica?
