Aspect of Greed

Flying, Indestructible
When Aspect of Greed enters the battlefield, you may draw 3 cards.
Whenever a creature you control does combat damage to an opponent, you may draw a card for each of those creatures.
If Aspect of Greed is put into your graveyard, discard your hand.
If you have no cards in hand, sacrifice Aspect of Greed.
A heavy price to pay.
