Spells and abilities your opponents control can't cause you to discard cards or sacrifice permanents
+1: Choose a nonland card name, then reveal the top four cards of your library. Put all cards with the chosen name from among them into your hand and the rest into your graveyard.
-3: Return target card from your graveyard to your hand.
Seriously, I think it's supposed to make her look more scholarly. It misfires a bit, I'll admit.
Would even help you to acquire auras that you need. Need an aura that grants vigilance? Name the aura in your deck and hope to hit it with +1. If not, you just got through 4 cards that wouldn't have helped you. Need one that gives your creature flying, but you milled it with the +1? Just use her -3 to get it back.
Name a card, any card. Doesn't matter because you got an effective Draw 4 for +1.
