While my opponent decides what this turn's purchase will be, I realized that the synergy Goons and Worker's Village is probably key to winning this game, but I don't have any Goons, there are no Goons left in the supply, no Goons in the trash, and all of my opponent's Goons are on his Island Mat. But by the time my opponent is done deciding, I've already realized that's A-OK. A dozen turns later, I play four Goons in a turn and pile out the Estates for a win.
What happened?
