Quarry is fairly straightforward in how you would play it. It only lowers the cost of action cards, so it is like a Gold for buying actions but a Copper when buying Treasure or Victory only cards. And unless you are getting a large number of actions, it is likely to be the same as Silver since you often end up overpaying anyway. It is helpful with plenty of +buy from other cards and cheap actions, such as Hamlet, or if you want to get a high cost action card quickly like Forge or Expand. It is particularly strong in Kingdoms with Grand Market since 2 Quarries is enough to buy Grand Market, which quickly leads to turns buying multiple Grand Markets for a quick economic explosion.
