You should really consider to fix the shuffler. I don't think you intentionally rig it, because I don't think you are technically capable in this, considered that the game has a lots of unresolved bug still today. Simply is too bad because of your incapacity. Please assume someone that is good in programming pc games and app. It's really embarrassing for you and your credibility having entire days of matches in which one screws and floods alternately. Effectively, I am embarrassed for you and your incompetence. It's almost normal, with the present shuffler, drawing half the lands of the deck in the first 20 cards, or only two. It happens in more than 75% of the matches. This is far far away from every realistic probability.
