Daily Quest - Earth Quest

Hi Friends,

That is what I have done at the beginning of every season; I spent a tremendous effort to reach the silver league. For achieving this goal, I need to battle a lot, because my average battles win rate is 50 something percentage. I found in my case, once you've reached the silver league, you are safe. It sounds easy, but it is not. Generally speaking, I rent lots of useful cards to help me escape cut throat battles and reach silver league as fast as I could.
