Risky Manuever

Discard two cards, draw four cards, then
exile a card from your hand.
Disarm 6 (Exile this card until you cast a card
with converted mana cost equal to six.)
At the beginning of each upkeep, if this card is
in exile, Risky Manuever deals X damage to you
where X is the number of cards in your
graveyard.
