Herald of Mordor

Extort (Whenever you cast a spell, you may pay {w/b}.
If you do, each opponent loses 1 life and you gain life equal to the total life lost this way.)
Artifacts and creatures your opponents control enter
the battlefield tapped. Whenever an opponent casts a
noncreature spell, that player loses 2 life and you
gain 2 life.

"My master, Sauron the Great, bids thee welcome. Is there any in this rout with authority to treat
with me?"
