Ahri, the Nine-Tailed Fox

Lifelink, Vigilance
Spells and abilities your opponents control can't
cause you to sacrifice permanents. Look at the
top four cards of your library. You may reveal
an Aura, creature, or planeswalker card from
among them and put it into your hand. Put the
rest on the bottom of your library in any order.
