Doesn't say that. Anywhere. Nobody knows how she actually throws the blades, it's left to the imagination. Claiming that she doesn't use wind because she uses her mind is baseless because nowhere does it say she uses her mind. That's just an assumption you've made. She may well use wind. Then again she may not. Until Riot confirms one way or another, we simply do not know what form of power she uses.
