The best way to climb through the leagues is to actually play the game. After finishing Bronze last season I played a little more (not a lot more) and managed to get up into Silver.
15 Chests... that's starting to feel more like actual rewards again. Maybe I will play my way into Gold this Season.
Quite a few actual cards in the mix. Decent rewards, I suppose!
