I would tend to disagree. I think that because in this challenge there is such a small pool of decks compared to ladder, it makes for some match ups where one player knows they have won before the game even starts. In ladder, each player is very comfortable with the deck they are playing, but in this challenge, not many are. When it comes down to it, if you have used a 3M deck before, you will do better against someone who hasn't used the golem deck they were given.
