some other comments:
- one of the five cards without a single submission was pretty easily in the top half of submissions last year.
- totaling the cards from every submission, alchemy and corncucopia somehow have the exact same number of cards submitted. hinterlands, prosperity, and intrigue are all within 6 submissions of each other.
- counting the promos as an expansion, the average kingdom submission would require 5.7 different expansions to play.
- kingdoms with an attack card tended to include another attack card, with 1.7 attack cards per kingdom with at least one.
this should be enough to keep you guys going for a little while. i'm also putting together some numbers for kingdoms with various options (terminal draw, plus buy, alternate VP, kingdom treasures, etc) but that isn't ready for all the options i was planning yet.
