Desecrated Grave

You lose 2 life and draw 2 cards. Discard two cards unless you have 7 or more cards in your graveyard.
If you lost 7 or more life this turn, each opponent loses 2 life and you gain life equal to the life lost in this way.
Flashback - {7}. You may exile up to 7 cards from your graveyard, each reducing the Flashback cost by {1}.
