Vex'ahlia

Vigilance, Reach

If Vex'ahlia would take combat or noncombat damage this turn, remove that damage, this ability triggers once per turn.

Whenever Vex destroys a creature you don't control with flying, you may look at the top X cards of your library, where X is the power of the flying creature that died, you may reveal one nonland card from among them with value
X or less and put it into your hand, put the rest on the bottom of the library in a random order.
