Apparently there is an exploit that can be used. Recently I played a match against NR player and I passed up the round. He started putting in all of his cards and made a combo Redanian Elites and reinforced Ballistae. When Elites went golden and balistae started to hit my units I instantly got a message saying something about a sort of inconsistency detected and I lost the match. That s-bag used all of his cards meaning he knew about it and is using it to win matches instantly 2:0 defeat even though that was the first round
