I've noticed a trend of many cards making 1/1 flying Thopter tokens (almost to the point of blatantly copying Magic Origins), and some cards making 1/1 nonflying Thopter tokens. It would be confusing for there to be both flying and nonflying tokens; Thopters naturally fly. I feel like the non-flying 1/1 artifact tokens should have a different creature type, like Golem or Automaton or Construct. Also, if this card is intended to be a homage to Doomed Traveler, it would make a flying 1/1 token.

They all make 1/1 flying thopters. If some wordings omit the flying keyword, then it is simply an oversight on our part.

And yes, we are reusing the thopter theme from Magic Origins because it fits with the theme and mechanisms of the set. Even if some cards have similar designs to that of Magic Origins, the different environment will make it a new experience. "Blatantly copying" is offensive, especially considering that WotC constantly reuses successful themes and mechanisms from one set to another.
