Decipher - The Art of Great Games
This is the card that cost me the tournament on Saturday.
I had my usual Federation 2-Mission-win deck running with a couple of improvements.
In the first round I was paired with Bruce and his Borg deck.
I've played him a couple of times before, but his Borg deck was always clumsy and slow, and didn't really pose much of a threat to me. I also knew the holes in the Borg affiliation that I could exploit as far as Dilemmas were concerned, so I wasn't worried.
He attempted his third Mission, I used my first Dilemma (Harsh Conditions) to block his Locutus then gave him a sure-fire Dilemma targeting Diplomacy or Law... no way out, he was going to fail the attempt, and I was going to win on my next turn.
Then he produced Ascertain. I hadn't seen it before... somehow I had overlooked it upon inspecting the card list of the latest expansion. He replaced the Diplomacy requirement with 2 Programming and easily slipped past with the Borg abundance of Programming Personnel.
There was much swearing.
I ended up in 2nd place.
