LeBlanc, the Deceiver

Flash, mage
Whenever LeBlanc would be put in your
graveyard, look the top card of your library, then
say a card name. Your opponent must guess if
you told that card's name. Reveal that card. If he
or she guess wrong, untap up to two lands you
control, then return LeBlanc to the battlefield.
"The Black Rose shall bloom once more."
