You know, just talking off the top of my head without any knowledge behind it whatsoever

, perhaps one of the problems is that to compete effectively in the "high-stakes" tournaments, you only use a "handful" of cards out there, thus getting a handful of decks. What if there were so many decks that it would be nigh-impossible to test your deck against beforehand? Obviously it would be frustrating, as you have no idea how your deck will perform, but then, isn't that kinda what you do against a stranger in a "casual" game anyways?
Maybe the solution is that tournament decks need to follow Starter deck format or tweak the number of rares/uncommons. Maybe the number of cards allowed in a deck needs to be looked at again. Maybe there has to be a rule that if a decklist can be found on the Net (or by 2 or X number of sources) it can't be used and the top 4 or X decks finishing are added to the list. Who knows?
