The Curse of Dierverk

The Curse of Dierverk can't be countered.
When The Curse of Dierverk is cast, exile all

Put X black 0/1 creature token cards with shroud
onto the battlefield, where X is the number of
creature cards exiled by The Curse of Dierverk.

here can the curse leave us alone."-King James III
