I am going to make a pretty big claim here and say that Wizards is overestimating the power and value of card advantage. A simple way to show this is the power creep everyone knows and talks about. Since after Ancestral Recall was realized to be a massive mistake, the power of card draw/dig effects has remained relatively static. On the other hand, cards which establish a board position, such as creatures but also other permanents, have had an unsteady but strictly increasing power level.

I'll even argue that board position is a much more important determinant of winning than CA is. agree/disagree?
