Deathly Pact

Draw two cards then exile your hand.
Exile Deathly Pact to a creature you control instead of putting in your graveyard.
When the creature with Deathly Pact exiled to it dies, put the cards exiled with Deathly Pact then exile a number of them so you have a maximum of 5 cards in your hand. Shuffle the creature that died and Deathly Pact into your library.
