Smash Apprentice
Not sure if this idea was proposed, but with the stage builder, a new type of tournament is possible. In this tournament, the organizers would create tournament legal (we'll have to wait until those standards are clear in brawl) stages beforehand. During the tournament, these would be the only available stages to play on, and players would not get to see these stages until the moment they begin fighting. Of course, mastery of certain set stages is a skill in melee, but learning a new stage quickly is another skill that can be tested with this type of tournament.
