Although it may seem that it is geared toward beginners, what I find is that it is geared toward those who haven't done a prerelease before. There is a difference. The real reason I say that is that it is quite the challenge to open the packs, and make a 40 card deck within the 30min limit. Choosing the right cards, weighing many factors is hard, unless you have some knowledge of what is in the set, and even then you may end up being surprised - like not knowing the Snorlax Lv X would be in the set. Also sometimes PTO's will run some of these challenges with full cards (give out the deck, and the packs, and tell you to tweek the deck), so hey, try it out. You may like what you see. This time the decks had some decent supporters (except for Mom's Kindness), so you never know what may happen.
