First battle chest I opened

Today I had the earth splinter and finished my quest very fast. I ended up in the Gold III league and got a treasure chest. When I opened the treasure chest here is what I got.
Not exactly thrilled I think that these potions are just snake oil. Every time I use them I dont seem to get very good cards... every time I skip them I seem to get better cards. Very disappointed that I dont get as much value as before when I do my daily quests.
