Its decent, but something is seriously wrong with your randomizer!!!!! Several times i have drawn 7 lands and 5 creatures, when the deck has twice as many creatures as lands. Some cards are literally in my opening hand 95% of the time, while other cards never show up when the same number of cards exist in the deck. Yes, this does happen in the real card game, but rarely. The amount it happens in the mobile app is just insane.
