I was playing on my friend's account a while back and my account at the same time, and we got matched against each other in pvp 2 but I cancelled the search on my friend's account. I ended up getting the game, and he didn't meaning the ai took over and he didn't get a loss when I beat him. Most people on the forums probably already know this but I thought I should post about it. Basically this 'bug' (if that's the appropriate term) can be abused and used for farming by making unwinnable decks on other accounts to gain free gold and cards.
