Mind Waltz

Target opponent puts cards from the top of his
or her library into his or her graveyard until he or
she has ten or less cards in their library. For
each card put into a graveyard this way, he or she
loses 1 life and you may draw a card.
"I'll lead the dance. Don't worry, I'll make sure you
follow."
