I don't have -that- much desire for crack ship when the canon-hinted ships are so delicious. But I like Ho'olheyak/Muelsyse, they have potential and thematic parallels (is it even crack though?). My friend sold me that Surtr/Arene interactions can be very fun, so I'm with her on the boat. And Pozyomka/Heidi is one I find very visually cool and fun to watch. I'm sure I have a few ships I like the fandom would be surprised at but that aren't technically "crack" when there's base to jump off from in canon.
