I agree with you gentleman, another Mystery set would be special. I would like to see the 2000s or the 1950s. Though my number one idea is for a POST WAR MYSTERY SET covering say 1945-1999.
They would already have most of the cards needed except for the 1945-1959 period. And think how big the player pool would be. It would mean no more bad auto drafts where you miss on half your picks.
I don't think we will be getting anymore Mystery sets but if we do it will probably be the 2000s. As much as I would like to see more Mystery sets, I won't hold my breath.
