Can the Advisors reveal a 'when played' card that I hold in secret, or must I reveal one if I have it?
One player's reply is the only answer we found; it is a best reading.

If you have a legal card to reveal, you must show one, since the rule is not written as optional. If you have none, showing your hand is the usual way to prove it. This is a convention, not explicit rules text.
