Memory Leak

Enchant player
As an additional cost to cast Memory Leak, discard a card, then put the top three cards from your library into your graveyard.
Enchanted player's hand size limit is 0.
When enchanted player would draw a card, you may pay {1}{b}. If you do, that card goes directly to its owner's graveyard instead.
Alzheimer's? Ha! That's child's play. When I'm through with you, you won't even remember how to walk.
