I have noticed that while playing 60 card, best of three on PC, the shuffler is noticeably worse. While using decks that would otherwise perform normally in best of one (consistent 2-4 lands in starting hand, even mix of land/nonland draws), whenever I play best of three, those same decks almost always receive horrible hands and draws (0-1 or 5-6 lands in starting hand, multiple instances of consecutive land/nonland draws). I know most people have issues with the shuffler in general, but I don't really mind how it usually is. That being said, specifically for best of three, it feels like the game is actively trying to ***** me over. My circumstance might be hyperspecific, since I only really play this format with my friend in challenge matches, but it is quite irritating.
