Adam, I agree.
Regular sealed is very luck based, but increasing the packs simply increases your chances, does not take the luck away.
It was VERY interesting for me to have a sealed event where everyone was given the same 2 theme decks to build a 40 card deck....120 card pool, only able to use 40, made things very interesting.
I would like to see something along those lines, which would benefit, and test the deck making skill of the players, not just their luck in the packs. Let's face it, there are some Broken cards that really give a large advantage to anyone who would pull them (Mewtwo EX, ZapdosEX, Manectric EX among others)
There is one item that would accomplish this....the Battle Stadium. You would have a pool of over 180 cards with which to make a 40 card "sealed" deck. You know what your opponents have. You even have a good trainer engine! (TV Reporter, Dunsparse, Bill's). Do you play just Blaziken, just gardevoir, or take a chance on some of the other lines....such as the Seaking line to counter Blaze? I think this would mark the ULTIMATE in deckbuilding skill. Other big advantage - no need for energy - you are given energy in the Battle Stadium, and you use what you have (maybe offer every player 4 of each energy not in the stadium)
Time would not be a factor...you still have the same time to pull the same cards.
Who knows, maybe we will be surprised, and there will be a "draft set" that will come out, where everyone will pull from the same 100 cards.
Just my crazy, vision, humble opinion.
