You know what would be cool: a older set, not necessarily a money set, but something like Coldsnap for all the random fun/EDH cards. But I don't want to add it to this poll which is really standard boxes
Wizards don't print anything that isn't in standard (and even then I've heard they've stopped on DKA because of poor performance). So the only boxes that are easy to source will be INN/DKA/AVR, M13, or RTR/GTC
