Cooke, Profane Purveyor

Haste
{u}{b}{r}{t} Discard your hand: draw three cards,
you may play a card discarded this way from
your graveyard this turn by paying life equal
to its mana cost.
Sacrifice Cooke, Profane Purveyor: until the end
of your next turn, colored mana symbols on
spells you cast may be paid by paying two life
instead.
