Et, Iz-Mystic Nova

Flash, flying, haste
Et, Iz-Mystic Nova's power is equal to the number of instant and sorcery cards in your graveyard.
When Et, Iz-Mystic Nova dies, you may exile it from your graveyard. If you do, each player shuffles his or her hand and graveyard into its owner's library, then draws seven cards.
