So I played a game today against someone who started by rushing the Fool's Gold with no +buy support. It seemed a little silly to me (if nothing else, she could have gotten a Margrave fairly early and made up for it by buying multiple Fool's Golds on a later turn). I sniped a few to keep her from having all 10, but mostly I was rushing the Ill-Gotten Gains. By the time I'd bought seven IGG, she already had two Provinces, and suddenly I'm like, uh-oh, if I finish rushing the IGGs she wins because that's three piles. And I was building a deck organized to rush Duchies, not compete for Provinces. I picked up an Embassy, but so did she, and though I was able to grab a couple of Provinces, she ended up winning by two points.
