Deathly Pact

Draw two cards then exile your hand.
Exile Deathly Pact attached to a creature you control instead of putting in your graveyard.
When the creature with Deathly Pact attached to it dies, put the cards exiled with Deathly Pact into your hand then exile a number of them so you have no more than 5 cards in your hand. Shuffle the creature that died and Deathly Pact into your library.
