I think it's interesting to have a card do something when revealed, but i'd rather have it do something negative. Hunting Party and discard-all Tunnel strategies are good enough already, and if you make it do something bad, i imagine it would change balance in a very refreshing way (it would also strengthen weak attacks like Spy and - if it's a victory card - Bureaucrat).
