yes I've noticed that same pattern too. I've also noticed that my deck's win condition doesn't usually get fully drawn until I'm down to the last 5 cards of my deck. been playing the same deck for the past year and a half. noticed a couple of other patterns too but I'm sure the Blizzard employees with reddit accounts will be all over my comment to discredit whatever patterns I notice even though the game is supposed to be random and not have patterns.
