Okay, weighing in more meaningfully now.
I largely agree more than Aaarrrgh than with Pavor: I'm open to the idea of Magic doing a cyberpunk setting, especially since "Cyberpunk with magical elements" is a pretty well-established subgenre/aesthetic.
Shadowrun first came out in 1989. I may be personally biased because the next manuscript I'm working on refining (into a trilogy) would fit that kind of vibe, where there are robots and mechanical implants, but also witches and demons, and things that blur the line by being magitech like handing "uploading" a person by using advanced scientific machinery to produce a phylactery for the soul. So for me to say that the basic idea of the blend is something that wouldn't work would be beyond hypocritical.
Further, I remember in the 90's and early 2000s really enjoying the fact that Magic did blur the line between what counted as Fantasy and what counted as Scifi. Sure,
Alpha and
Legends and even (to me) attention-grabbers like
Fallen Empires,
Ice Age, and
Homelands did pure periodesque Fantasy, but a lot of the really unique stuff, like
Antiquities and just about everything Urza, Rath, and Phyrexia didn't. It was Magic's relationship with Artifacts and Technology that really set it apart from other Fantasy of its day. We've got killer cyborgs*, nanomachines**, space stations***,
Mechas, mobile robotic cities with doom cannons****, questions about whether an artificial being can have an authentic existence*****, and that's just in Magic's heyday, before we really left Dominaria. Hell, the entire thing about the Thran is that they were an advanced technological society that didn't understand magic as magic. Old MtG reveled in Clarke's Law and the Inverse and loved pulling them on the characters sometimes and the fans at others.
Frankly, the idea of integrating impossible tech with functional magic is something that's been largely missing as we've been going plane-hopping to the Hammer Horror Studio Backlot or Epcot Greek Myth World or the Holodeck rendition of Prince of Egypt, or Zendikar and Ravnica intolerably many times. Even the groups that do it, like the Izzet and the Skaberen, they're presented as mad and weird and one-off and mostly just slapping gears and Jacob's Ladders on things because it looks cool. I actually think that Kaladesh was one of the planes we've visited since Time Spiral that was most true to the spirit of what made M:tG great... it was just marred by an intolerable plot.
So, in that sense, I'm kind of open to seeing a cyberpunk (and I hope truly cyberpunk, with full tech as well as the inevitable true magic) plane. And in a sense it does kind of make sense to do it with Kamigawa. I think most people would prefer a new plane if it's going to be so different, but out of anywhere recurring? Because of how ingrained a Chinese/Japanese influence is on the modern Cyberpunk genre (perhaps because loads of genre cornerstones are Japanese media and many Cyberpunk stories predicted China to replace the west as the preeminent world power), if you're going to pick one plane we've been to before and say "here, this is Cyberpunk now", Kamigawa is the one you pick.
And I'll say, while I'm not absolutely thrilled, I am... open to it. I want to see how the Kami interact with a world that's changed. I want to see some indulgence in things we didn't get to see last time, like modern(ish) Yokai and Japanese Urban Legends, which often take place in the kind of big city environs that Kamigawa 1 didn't present. We got plenty of classical Shinto, and it was amazing, but we didn't see Nurikabe, or Kuchisake-onna or Hachishakusama that have a home environment that's either more urban than old Kamigawa was, more modern, or both. (Aside: I REALLY want to see a Nurikabe with the typeline "Spirit Wall"). But I don't think anyone wants to see a modern Kamigawa or even a Showa or Meiji Kamigawa And I think we could get some wild and crazy stuff, like maybe using the shattered yet still eternally living shards of Lord Konda as the core of a supercomputer. That would tie back to dangling threads of old kamigawa and give them a new spin. It would be very cyberpunk, taking this old dead villain (not exactly dead in Konda's case) but having them live on as the ghost in the machine, granted no real physical body but an astounding intellect and presence. And it would be a neat spin to revisit Kamigawa with, bringing back Konda in a form that's consistent with the one we left him in.
I think we could do it. I think Magic has the technology if it has the guts to have something that's got the Cyberpunk flair, the Kamigawa feel, and that shows us something new and different that's still part of magic. Hell, just typing this out I thought of a design, have a card named "Kotoribako" that's an oppressive stax artifact and looks like this grisly mechanical puzzle box with lighted seams, oozing blood over the glimmering steel surface. Something like that would, like Kamigawa 1, take a Japanese story that not many westerners are familiar with, represent it in mechanics and flavor, and interpret it in a somewhat new and unique way that would belong to M:tG as well.
That said, there is one thing Pavor said that I absolutely want to reiterate, with which I 100% agree.
If "just make it cyberpunk" is their excuse to not have to deal with traditional Japanese culture in their game anymore, I never want to read or hear anything about "diversity", "respect" or "cultural sensitivity" from anyone in that company anymore. Not that I want that as it is, but the hypocrisy would reach a new high.
Many years ago, speaking to the difficulties of returning to Kamigawa, Mark Rosewater made the statement that "People love beef teriyaki". Pointing out that, while Beef Teriyaki is considered quintessentially Japanese, it really is a fusion cuisine, and a fairly modern invention at that. But, all the same, if you visit a Japanese restaurant, you expect to find it (Aside: He's wrong. If you go to a moderately authentic Japanese restaurant, not Benihana, you may well not find Beef Teriyaki... but I'm sure there's some other dish on the menu of any of my favorite places to eat pre-Covid that could still make the point, except possibly the conveyor sushi place...). The takeaway was, basically, that one of Kamigawa's faults was that it didn't do enough of what people expected. There should have been more ninjas, more anime tropes, and so on. This same sentiment, I feel, would go on to inform a lot of worldbuilding that we here in the NGA F&S area have found... lackluster, or at least been divided on. Things like Theros, and especially Theros having Krakens in particular bowing to pop culture memes centered around
Clash of the Titans. All the precise 1:1 references in Theros and Eldraine to the earthly stories the cards were based on -- things that have typically been very hit or miss, because they risk being too on the nose
But, I think, especially returning to Kamigawa
so much later (in real time) that the authenticity of the place, long and possibly erroneously cited as a weakness that led to its poor numbers (numbers that likely had a lot to do with it being a parasitic, underpowered block sandwiched between Mirrodin and Ravnica), is what made it so very enduring in the eyes of fans. People held on to Kamigawa. Even though it was pretty well liked overall I don't see a lot of calls for a return to Alara, for instance, and while I would personally love another swing at Ulgrotha I doubt it has quite as many devoted people. It showed westerners something developed, deep, and steeped in a wonderful lore that would be alien to most but engrossing because it still touches on very deep ideas, just as lensed by a culture with which most of the market for Kamigawa wouldn't be intimately familiar. It became a cult classic for a reason. If you revisit, and advance the setting to the point where we are cyberpunk now and KondaOS's secret police clash with motorcycle-riding Shinobi on the mean streets of Neo-Eiganjo, that's fine... as long as there's still that deep backbone of authenticity. As long as it's not
all Beef Teriyaki. Sure, people love Beef Teriyaki, but if I go to a Japanese Restaurant I don't expect to see
nothing but Beef Teriyaki. Maybe I want the Unagi, the Kakiage don, or the Tonkatsu Ramen. Those need to stay on the menu, or you lose the point of being the Japanese Restaurant.
If it's Cyberpunk, that CAN work.
If it's all Beef Teriyaki, we're gonna have problems.
