Sacrifice a nontoken permanent: counter target spell of the same type as the sacrificed permanent. If a spell is countered this way, exile it.
Whenever you sacrifice a permanent, scry 2.
Whenever you scry, Make a Pact. (To Make a Pact, sacrifice a nontoken creature, discard a card, or loose three life. If you do, draw a card)
