Just wondering what people thought it would take to actually create a massive shift in the vintage format, to the point where we see new innovations. We have seen new decklists and cards cards float in and out of the format over the years, and the majority of the time they don't really change much about the overall of the format. Many are just power level upgrades to existing strategies, bringing back a decktype that was sorta falling out of flavor, etc, but what would it take for something to reshape the landscape of the format?
Personally I think Dredge was the last time the format really got what could be considered a new deck and a format altering list, since it was a list that fundamentally changed the way we played, a list that didn't need power or dual lands or fetches or even force of will. You could play a dredge deck that was 60 cards and it could literally be 60 cards that had no cross over with the 60 you were sitting opposite of, not even basic lands.
Most of the stuff that we get now days that really garners any attention are things that hose popular decks in a profound way, like some speculate dampening sphere will do, or something that is just profoundly powerful like snapcaster mage. They do not create new decks or ways of playing, just reinforce what is already there.
Personally I think it would have to be an effect similar to what some of the digital CCGs are doing, some mechanic that is fairly unprecedented such as a card that came out of your deck at the beginning of the game or other pregame effect. Wondering what other unprecedented concepts people could come up with that are A) possible and B) profound.
