I keep hearing about the stage list being a component to their success, but I still have a hard time seeing the logic behind it. The argument I hear is that static stages are best for the Ice Climbers while more dynamic stages hamper their success. However, the most common thing in place of a best of three set with counterpick is that ICs can still play 2/3 of the matches on dynamic stages. The first match has always been played on a static stage of BF, SV, or FD. Apart from a few outliers, this is generally the case and has been the same way for ages about the first stage played. The following two stages are picked by each player one a piece. Since the beginning of brawl, its always been in the ICs favor of a 2/3 stages being static for them. I suppose that the reduced stage list might make it more of a 3/3 stages in their favor. Although, I suppose I'd have to hear what counterpicks from long ago were horrendous for the ICs compared to now with counterpicks that are bad, but not terrible like in the past.
Anyway... The idea of a great player backing a character might just not be possible anymore with how far the game progressed, but more frequent at the beginning of a games life. Again, I recall hearing from a couple people that Marth in the melee early days was also never much of a threat, but along comes Ken and shows people that this character can do stuff. From a novice standpoint, I still remember playing Brawl for the first time and thinking Snake was terrible. Come to the smashboards and see the Snake tier list ranking and thought "How is this character any good?" Then you see some matches and hear the specifics about his Utilt/Ftilt/Dthrow/Nades. I starting understanding a bit more about how you could use the character in ways I never saw myself. However, this is all a the infancy of a metagame. This far into brawl I think for any "great player behind a character" idea to work it would have to be with some really subtle refinements in how the character is played. Someone having skills at things most players have overlooked or not bothered to mess with either due to difficulty or simply not seeing its usefulness.
