Kench, Dealer of Fantasies

The Deal is Struck - {x}{b}: The next spell you cast this turn with mana value X has Bargain and has "If this spell is bargained, copy it.
You may choose new targets for the copy."

Collecting Dues - Whenever you Bargain,
you may Bargain an additional time.
If you do, put two +1/+1 counters on Kench,
he gains Deathtouch and Trample until end of turn.
