​I was just wondering.

If there is no magic is on the Isle, and magical objects, like the dragons eye, the magic mirror, and Mal’s spell book, don’t work on the Isle, why do the Uma and her pirate crew think that fairy Godmother’s wand will work on the Isle?

Hasn’t Fairy Godmother thought of that?

If you know the answer to this odd question, please tell me in the comments down below, and thank you.
