Ok i know that Maddie is a clone of Jean. and there is a list that describes Maddie's powers. [no i won't tell you the website.] I think that selene taught her the skills of Sorcery. Did Sinister give that ability to her during the cloning process? Or is it a potential that jean has?
Here it is about Maddie's power.
Sorcery: Madelyne possesses the ability to cast a wide variety of simple and complex spells. Her sorcery might is such that she has been shown to restore life to the long dead.
