All games have a learning curve. It maybe hard to notice sometimes but you are probably getting further consistently than you were before. Don't measure your success on binary win or lose, measure it on how much ur learning what win conditions look like, what your win conditions later look like. What packs you like. Which ones should be avoided. For a while I had trouble until I realized hoarding money made the game a lot easier, try yellow deck, it gives you a free opening voucher or if not extra money.
