I always thought they had to be dead first, now I don't believe that. I think it is some kind of special magic that we haven't seen the mechanics of yet. He had control over her sight with the poison.
That's the thing this scene is so weird because Arya didn't drink the poison, the person who we thought was the jaqen h'ghar drank it, but then it turned out it wasn't him and that mean girl was...so yea either they do have to be dead to take a face/shape shift and they somehow were able to play w/ Arya's eye sight for a trick, or they don't have to be dead to shape shift/take faces. Either way we clearly don't know enough about their rituals/magic and the implications there in.
