High Shadow of Grixis

Flying
Whenever you pay life, draw that many cards
then discard that many cards.
Each Demon creature card you own that isn't on
the battlefield has madness. The madness cost is
equal to its mana cost. (If you discard a card with
madness, discard it into exile. When you do,
cast it for its madness cost or put it into your graveyard.)
