Well that took a while! I finally made it to Gold League and while I'm currently only Tier 3, the competition is much harder. I suppose it's because I took a couple days off playing and so now I'm catching back up to those who had advanced before me.
The good news is, the Daily Quest rewards are much better in the Gold League. Even at Tier 3, I get six cards each day if I complete the Daily Quest. So that's 50% more cards than I was receiving in the Silver League.
Here is my Daily Quest Reward for today.
Nothing fabulous, but now that I'm getting 50% more cards for Gold League, the odds that I'll be getting a really good card have improved by 50% also.
I like those odds!
