Nesephet, Night Overlord

Flying, deathtouch, menace, indestructible
When Nesephet, Night Overlord enters the battlefield, put all Demons from all graveyards onto the battlefield under your control.
Creatures you control have first strike and haste.
If Nesephet, Night Overlord would be put into a graveyard from anywhere, shuffle all cards you
own from exile and all cards in your graveyard into your library. Then, return Nesephet, Night Overlord to your hand.
