That's not true. All of their spells/abilities are within the Magic we've been told they have. Gray's Magic allows him to create things made of Ice so him using a new spell to create something new is withing his Magic, same with Lucy, Natsu, even Erza. but for the 380 chapters of this series, Take Over has been the ability to transform into a demon/beast/animal. and now suddenly in one fight Mira can also control other demons and can now take control of other's powers. that' bs.
