It would be nice to know how many cards are in the deck and discard piles. Cards such as Gardens are tough to judge when to purchase in virtual game play when deck size is not known. Even though you are not supposed to count your deck in normal gameplay, the visual thickness of the deck is a good indicator of when its time to start buying Gardens. It is also good to know the size of the deck or discard pile in general, in order to understand if you need to trash more cards with Chapel, for example.
