Voice of the Abyss

Blue spells in your hand have Flash.
Black spells in your hand have Madness {2}{b}.
Whenever you cast a blue spell, you may
draw a card.
Whenever you cast a black spell, you may Extort. (Whenever you cast a spell, you may
pay {u/b}. If you do, each opponent loses 1 life and
you gain that much life.)
