Mystogan never really could use magic. It was all in his staves in my opinion. Whenever he uses a spell, he was using his staves and his knowledge of the spells to use them, which is why when Jellal obtained the same kind of staves Mystogan was using, he could use the same magic. If he like everyone else had magic inside of him, then Mystogan would be insanely strong.
