I started using these premade decks and they really helped me... at first. I was haveing a 4-1 win ratio and then suddenly I stopped. For a few days now I have been losing. I hold on pretty good but everyone I'm playing against slams out legendary cards. a lot of them. Is this because I was winning so much? Will I eventually start winning again after I lose a bunch? I have to win to earn gold so it is really frustrating to be up against people who can play terrible cards one after the other.
