Yes, I’m aware that they change the stories- but they still have to follow some sort of logic! Giving Oz powers wouldn’t make any logical sense to the story. There is a difference between a clever twist and an arbitrary direction. I can’t think of a way that having Oz have real powers would make any sense.
But anyway- I agree, other realms such as Oz are not part of the curse…although I’m not sure how Jefferson got pulled in.
Pinocchio has been conspicuously missing since the pilot. We know Gepetto and Jiminy are in Storybrooke, and we know Pinocchio was around when they were building the wardrobe. His story has been part of the show since the beginning. You really think he just disappeared randomly with no explanation?
