It’s an Arena card and they left its wording intact, which doesn’t change much of anything.

It’s very similar to creating a token except that it interacts more with other cards than a token; the Clock he creates can go to the graveyard, be returned to your hand with Regrowth and then cast, etc.

Edit: It’s like a combination of tokens and Wishes (get a card from outside the game), and both of those effects have been in the game since 1993.
