Blood-Soaked Wish

You may choose a card you own from outside the
game, reveal it, and put it into your hand. If you
do, you lose life equal to its converted mana cost.
Until end of turn, you may cast spells from your
hand by paying life equal to twice their converted
mana cost rather than paying their mana cost.
Exile Blood-soaked Wish.
When payment is made in blood, weakness is the only
thing that can hold you back.
