There's no particular reason Wanda's powers have to be magical; for years they were defined as some kind of mutant power to change probability, and gradually shifted toward magic because the stuff she did didn't make sense either as a mutant power or a probability power. But if they're introducing her for the first time they can make her powers whatever they want.
