Zatanna. And I'm pretty sure I've given you an accurate representation of myself. [Because Logan doesn't really expect her to be overly polite and respectful, now does he?]

I've been using magic pretty much since I was born. As for actually fighting, I've had some lessons. Pretty steady ones for the past couple of months, plus experience fighting supervillains as part of a team of heroes. The same team my friend is on, by the way; her name is Artemis.
