Section 3: Specific Cards - I

Q. When I play INSUBSTANTIALITY, does the phrase "your next move" refer to your immediately following move within the same turn as when you played the card, or your next move on your next turn?

A. The move on the same turn.

Q. Can a PACIFIST Pawn capture by using IRRESISTIBLE FORCE?

A. A PACIFIST may use IRRESTIBLE FORCE, but not if it would result in a capture. It is also immune from being pushed off of the board.

Q. What happens when I use IRRESISTABLE FORCE to push an opponent's piece into a FORBIDDEN CITY?

A. FORBIDDEN CITY beats IRRESISTABLE FORCE. The pushed piece cannot enter the FORBIDDEN CITY, and therefore none of the pieces can be moved. IRRESISTABLE FORCE is still played, however; it just doesn't happen to accomplish anything in this instance.
