Z-edicts are cards designed to combat the use of a specific edict card. Each new Z-edict is played on an edict, and both cards are discarded.
All zap cards are covered by the Un Zap, an Eon edict from Expansion 8. The Un Zap should be classisfied as a Z-edict and is is suggested that you make another Un zap to balance the new Zaps. "and what stops the use of a Z-edicts", you ask? Why, an Un Zap, of course.
