I saw a lot of use of the cards, and I saw plenty in people's cases, but I didn't see any being used in competition. To be fair, I was pretty focused on my own matches because ... ****.... this was my first convention like this and there isn't really anything more overwhelming than keeping track of all your junk in a room with 150 other xwing players. It was a TON of fun, but I was curious about the lambda.
Did anyone see one in play at worlds? How was it used?
