Look... It was funny for about 10 seconds. Then you realized that not only was it just plain lazy, and absolutely stupid, but it made the game unplayable.
Did you happen to play TF during the "draven day"? Did you? If you didn't, then you don't know what unplayable is. If you did, then you were probably about to rage quit at the fact that the head completely covered not only your CARD color above your head. Sure, you could still look at the toolbar for the card color... oh, no your couldn't... because that is bugged. So basically, TF was just throwing a random card color. IMPOSSIBLE to pick a card.
