Quote from Richard Garfield on BGG
- I can't go into details, but the construction algorithm does reject decks and do small amounts of construction. In balancing the goals of variety against playability (both too powerful and too weak) we tried to cut as few decks as possible, but we did cut some. More often than too powerful or too weak was 'not fun', it is not fun to get a card that refers to Robots and then have no robots in your deck - or even just have one.
