Orzhilk, Orzhov Incarnate

Flying, extort, lifelink
Whenever a creature you control dies, you gain 1 life and target opponent loses 1 life.
Eminence -- As long as Orzhilk is in the command zone or on the battlefield, white creatures you control have flying, black creatures you control have lifelink, white and black creatures you control have extort, and creatures you control with the Orzhov signet on them cost {1}{w/b} less to cast.
Orzhov treasures more than wealth.
