I've been watching this free to play series on youtube:  https://www.youtube.com/watch?v=Jxht-L8vCng&list=PL6pNhtiaol0n9CUcpKkMKUtJ16cm-sV0e

Just wanted to share it because it has been interesting to watch complete n00bs at this game try to advance on the ladder, and i have been crazy annoyed by their misplays and bad deck building.  At the same time it's really cool to see them grow as players and in skill level, they are still not great and haven't gotten too high on the ladder yet... but its a really fun thing to watch.  It could be worthwhile for any new players or anyone who wants to remember the old days when you knew nothing about the game.
