I mean, some of that bizarre out-of-theme stuff weirdly works. And not everything needs to be tolkienesque. Innistrad, Ravnica, Ixalan, Kaladesh/Avishkar, Amonkhet, etc, all those themes can work together. And some other franchises fit that vibe, too, like Middle Earth, Avatar or even Warhammer 40k (surprisingly, idk how. Shouldn't work but somehow does IMHO), and I could see some others not yet scrammed into MTG that could work (Witcher?). Star Trek, Marvel, TMNT doesn't though. Maybe it's just because those are set in our real world (real places and names do something).
