Vinona, Skyseeker of Comoros

When Vinona, Skyseeker of Comoros enters
the battlefield, look at the top seven cards of your library. You may reveal an Aura card
from among them and put it into your hand.
Put the rest on the bottom of your library in
a random order. Whenever an Aura you control becomes attached to a creature you control, create a 1/1 white Human Soldier creature token.
