If you control a "Dark Magician Girl" monster: Destroy all face-up monsters your opponent controls.
Magician's Circle can be used to special summon a Dark Magician Girl from your deck, but you need an attacking Spellcaster-type monster, and this means that you can only use Dark Burning Attack on your next turn.
Legion can be used to tribute summon Dark Magician Girl in a turn, which can be used as a surprise, and using Dark Magic Attack can potentially clear your opponent's monsters, allowing you to direct attack right after.
