Muse of Sorrow

When Muse of Sorrow enters the battlefield, at the beginning of your next end step, each player discards a card.
Cycling {2} ({2}, Discard this card: Draw a card.)
Madness - {b}, Pay 2 life. (If you discard this card, discard it into exile. When you do, cast it for its madness cost or put it into your graveyard.)
Her song brings the chill of the grave.
