It would be very helpful to have statistical information for all decks displayed under the My Decks section. That way, you could see how many creatures, how many lands, etc. are in each deck. This data is all available; you just have to click on the deck to see it. E.g. when I’m considering whether I’m playing too many or too few lands in a deck, it would be very helpful to have an easy way to compare it with my other decks.
