Moku, Weaver of Weakness

Parter with Matla, Vessel of Power
Whenever you exile cards, reduce the cost of those cards by {x}, where {x} is the number of cards exiled, rounded down.
Whenever you cast a card from exile, you may draw a card, if you do, discard a card.
"Aww, Come on, Mokkie. Can't I have a little fun?"
