The lottery is very different, as it is truly based on random chance and anyone who plays has exactly the same odds of winning. As for the cards, I don't have a problem with it not giving me the card I wanted. I play the lottery as well and when I don't win I know this is because the numbers I chose did not match the numbers pulled. But when I pick a card in the Tavern and do not get the card I wanted I know it is because the game has predetermined, or rigged, the outcome. It is the removal of chance from the equation that makes it rigged. There is no chance element in this and that is what makes it rigged.
