I rate 0 stars for matchmaking everytime U win 3-5 games straight next opponent has every card to counter ur deck or just outright too strong River race and general matches is too much of a uphill battle in last 50 games less than 5 games I played opponents at my lvl....worst matchmaking game spoiled a good game,opponent game starts early,elixir generates 2-3 times faster,broken decks with hard to die cards ...
