She Who Asks

Flying, Lifelink
Whenever She Who Asks or another Sphinx
enters the battlefield under your control, exile
the top card of your library face down with a
riddle counter on it. You may look at that card.
Then target opponent may have you draw two
cards. If that player doesn't, you may cast up
one card you own in exile with a riddle
counter on it without paying its mana cost.
