Haughty Djinn was originally printed in DMU, and given that Dominaria has a long history of Djinn going back to Alpha, Smirking Spelljacker is probably from there. Older Djinn didn't really have a cohesive visual identity, but comparing it to djinn from the more recent Dominaria sets, it seems to match up
Out of all the Djinn in Magic, only two other in-universe planes have had Djinn, Ravnica and Strixhaven. Strixhaven is the other possibility, but Spelljacker looks pretty wispy which would align more with Dominaria
I think they're doing some Druid typal support in this set, but yeah I wish they'd try to keep tokens more Standardized across sets unless there's just no other way to do it
