I think according to the previous game, Herald tends to be extremely powerful on board without villages but some good engine terminals.
At first sight I think this card is UP, just a cantrip doing nothing if it does not reveal action. So when I did not see village I play big money and lose to Herald. Herald reveals another Herald is like a level-2 City. So, it looks very OP in such that kingdom.
Is Herald strategy always a dominant strategy on board without villages over big money? (Neglect rushes) If not, any examples of strategies beating Herald engine on kingdom with no villages?
