I was doing a ranked match. Or still am at it, in fact. The third round the opponent got disconnected several times for a few seconds. Then I got disconnected for a few as well, then he again. When the round actually began... neither of us could do anything. We can't play cards, there is no timer. At the moment it's just us... I guess, waiting, whoever of us disconnects first. I don't know. Perhaps he left already and the game is still showing a match, not a clue.
