There is no such thing as Enemy production. Please consider using some card effect that is actually supported.

You can replace "enemy production x0" with "enemy loses resources equal to his standard production", for example.

Oh, I see. Sorry. Right on it.

EDIT: Dark seal is now an Uncommon card. Even most uncommon discards do worse than blow 10-something resources and a single card(lich and dark templar pop up in particular).
