agreed - to a certain extent. the people who bought in now are the ones who could afford to buy up cards at random chances: whales, collectors, first wave of the community etc. but there are a lot of people who might have a shortlist of cards they desire, but didnt find it worth it to dish out thousands of dollars to get them. for those players the market will be a way of affordably acquiring the cards they need and offloading the ones they dont need. I think this will be the majority of players and that all those little shortlists combined will definitely bulk up on the more popular cards.
as for the diamonds and such - heh. time will tell xD
