Actually this is a great article because there are decks that don't consider CA as too important, aggro decks tend to fall into this category by over extending themselves with board presence. Putting down your whole hand by turn 3-4 and watching it all vanish to Terminus or Supreme Verdict while your opponent still has an almost full hand. I believe that this article helps to point out that careful use of your resources is also very important. If you can win with Lingering Souls by playing it twice and holding a second, then why not do so. Great article.
