There were a lot of choices in this game. With Black Market and Tournament, there were lots of things to buy. I was initially thinking I'd go for Gardens with Black Market and Council Room to power buys, but quickly realized I wouldn't be able to empty three piles, so shifted to Provinces. Much later, the Gardens come into play.
The ending is tight, and both players hit auspicious deck sizes on their last turn.
