As of the first day of previews, we have seen:
- 5/25 kingdom cards, 0/25 sideways cards, 0/12 wooden cubes, 0/6 playmats, and 0/35 tokens
- 0/3 Treasures, 0/2 Attacks, 0/2 Duration cards, and 0/1 Reaction
- 0/15 uses for tokens
- 2/16 uses of "trash"
- no card with a word in quotation marks on it
- no card with only 3 words on it; a card with only 4 words on it (Scholar)
- 0/3 ways to play Actions in your Buy phase
- no way to take a turn after the game would otherwise be over, unless you count returning Experiments? I'm sure that's not what it's supposed to be though.
- no trasher you can't turn off
- nothing that cares about shuffling
So not much yet, but it's still fun to do this. We'll probably see a lot more of these once the previews get into the on-theme cards.
