So, a couple of months ago, I played someone and at the end of the game, in the log it displayed he had a deck tracker. Essentially, he used it several times to keep track of what was in my deck. During the game, he was able to keep this secret. Does anyone know about this? Did the person make this himself? Is something like this floating out there, and if so how many people are using it. I won that game, but I had no notice at all or my permission that he was using this app to track my deck.
I can't remember who the player was. And, I did not say anything at the time because I was not playing Dominion much, but I was kind of surprised that this thing existed.
