I would definitely bring back the three shadow races as well in some shape or form (and the Shadow mechanic itself, ideally), though I have to admit that I like the Dauthi and Soltari much better than the Thalakos. In fact, there's hardly a thing about Rath that I wouldn't be happy to see on Dominaria, so as long as the execution is decent, I shouldn't be too hard to please on that front.
Having said that, Flowstone would probably be my number one incluson, partly because it's a really iconic part of Rath, partly because it should be pretty easy to implement in various ways. Heck,
Flowstone Giant was among the first three Magic cards I ever owned, several years before I actually got into the game (or was even old enough to do so, for that matter). Now, Flowstone has the "
: +N/-N" abilty attached to it, and IIRC, Maro said that red doesn't get that abilty anymore, but honestly, I'm sick and tired of the useless constraints they keep making up for their card design and that end up being at odds with flavour. Card design as a whole has come a long way and I'm really grateful for that, but there are certain things that will forever rub me the wrong way. I want my Flowstone, I want my original Slivers, I want my Regeneration, and I want my Flanking... (Speaking of Slivers and Flowstone, I'm genuinely shocked that we never got a Flowstone Sliver that gives that ability to all Slivers.) A small dose of Flowstone would probably be enough to make me happy, and it could mostly be in art, flavour text and story, but two or three cards that deal with it mechanically shouldn't be asking too much. Could be a creature, an equipment and an aura, something like that. I just love the flavour of that stuff. It would actually be cool to see a new legendary character who is adept at controlling Flowstone like the Evincars of old.
I think one thing that's really handy about the Rathi elements is that you could use them to fill some gaps in Dominaria's worldbuilding, that is, drop them in regions that don't have much else going on. The
Kor Haven in the Balduvian Steppe is a great example of that. It adds a new thing to New Argive that gives it some more depth and identity, and I really could imagine a loose alliance of sorts between the kor and the rest of New Argive. Sure, there probably is enough material about New Argive to work with anyway, but the Balduvian Steppe would be a pretty blank spot otherwise. Have the
en-kor roam the steppe and fight off Slivers, orcs, goblins, something like that. Their mounted lancers look like they'd be perfectly suited for the job. So yes, it would be awesome to see some kor as well, especially as a contrast to those on Zendikar.
Speaking of kor, I'd love to see the
and
il-kor as well, especially in Urborg where they ended up after the overlay. Now that Belzenlok is gone and the Cabal aren't as powerful there anymore, we could see a bit more diversity in Urborg, not just Cabalists and fat little swamp spirits (in fairness, the panther warriors are awesome, too).
One aspect I'd also consider is the fact that most things on Rath originally came from Dominaria in the first place. Take Skyshroud for instance. Yeah, it's gone now, but we know it started out as a floating forest in one of Dominaria's oceans, so who's to say there aren't others like it still out there somewhere? I guess they've set up the edges of Yavimaya as Dominaria's trademark aquatic forest, and that's cool, but it would be a great easter egg if they simply showed a floating forest in the background on a piece of land art.
The Dominarian origin of the Soltari is also alluded to in
Bloodlines (another shout out to Squirle's blog for pointing that out). It comes up when Urza encounters Lyna of the Soltari on Rath. I grabbed my copy of the book to look it up, and it says that Soltari was the name of a small city-state that "mysteriously disappeared back in the days when he and Xantcha had worked to free Efuan Pincar from the Phyrexians" (that's in chapter 25 of the book, or p. 743 in the omnibus edition). I think it's safe to assume said city-state must have been somewhere in Gulmany then, or Urza probably wouldn't have heard about it disappearing. What is interesting about this is that it might allow us to trace the origin of the other shadow races as well. The
Duelist had some information about them (reposted here:
https://www.mtgsalvation.com/twitch-log ... rt-stories and here:
https://www.mtgsalvation.com/twitch-log ... rt-stories). It used to be freely accessible, but the link is kinda blocking people that aren't signed in now, and I couldn't find it again by searching the site or using the Wayback Machine either. But I remember the Soltari being at war with the Dauthi before they were both taken to Rath, which is alluded to in the flavour text of
Soltari Crusader. I also remember the Thalakos being caught in the middle, though I can't 100% confirm whether that was the case
before they came to Rath. It probably was, though. The article also says (and you can check with Squirle to confirm:
http://multiverseinreview.blogspot.com/ ... mpest.html) that
Shadow Rider is one of the Dauthi who were still on Dominaria! What I'm getting at is, all three races probably came from Gulmany originally, and at least some of the Dauthi remained there. There is even a creepy adviser named Digody in
Dark Legacy whose race nobody can identify. He looks kinda human, but very pale and skeletal thin, with a hatchet-thin face and red eyes that sometimes glow. I like to believe that guy has a Dauthi somewhere in his family tree, considering that novel is set in the part of Terisiare that later became Gulmany...
I'll leave it at that for now, but the bottom line is, it might be cool to see some remnants of the Rathi stuff from the time before it even ended up on Rath. I realise that the shadow races are probably way more interesting in their post-Rath incarnation, and you kinda have to avoid redundant doublings of pre- and post-Rath elements. But maybe they could mention it in anther podcast or on a piece of flavour text. On the other hand, if they decided to complelety take away their shadow properties (and, by extension, the Shadow mechanic, which would be a shame), they might as well have them return to their ancient homeland and rebuild their old settlements or join their long lost relatives. Gulmany looks like one of those places that could do with some filler material as well...
