I'm not sure what the intention of this card is. A kingdom victory card usually either has a couple VP as a bonus on an otherwise compelling dual type card, or it encourages decks which stray from the standard Province approach in novel and enjoyable ways. This card handicaps itself in such a way that one can never obtain more than 25 VP worth of Pyramid -- so Provinces cannot be flatly ignored -- and its action feels awfully close to Bishop, only substantially weaker regarding VP. The best combo appears to be with Rats, but even five Pyramids and twenty Rats only gives 45 points. This is not enough to beat uncontested Provinces, especially since you cannot make use of Duchies.
