As much as I'd like to see them introduce Ozma, I really do think it would make more sense for Zelena, and it would also give her something to do rather than introduce a completely new character while there are still characters doing nothing :P (Dorothy would also be tolerable in this case.)

Although there is one hole in the theory: based on Gideon's speeches, there can only be one Savior at a time (he can't save the Dark Realm unless he kills Emma first). Aladdin is an exception since he lost his powers. So unless Gideon is wrong, that means any other Saviors we'll be seeing will be flashback only.
