If a card copied by the token had any "when [this permanent] enters" abilities, the token also has those abilities, and they'll trigger when it's created

While Cinderella works especially well in decks that focus more heavily on princess characters, she also does let you trigger her effect by just playing her, making her a solid draw/ink engine in-and-of-herself
