Maker of Madness

When Maker of Madness enters the battlefield, shuffle target creature an opponent controls into its owner's library.
When Maker of Madness attacks, the defending player puts 6 cards from the top of his or her library into his or her graveyard. If a creature with the same name as the one shuffled into its owner's library by Maker of Madness is put into a graveyard this way, that player discards a card.
