The fact that Regina have been acting "good" does not make her any less powerful, she can even produce light magic now (which in fact is stronger that dark magic, after all it stopped Zelena). So they might have to come up with something new for Maleficent, not even her staff seemed to be special in any way (one might think that it makes her stronger, like with Jafar, but this was not the case).
