I've made it to the Gold league finally, just before I finish my daily quest. I have some potions right now, so the more rewards cards I can get, the better... hopefully. Some of them aren't so great, but some are awesome. It just depends.
I finished the quest in the Gold league and got more cards.
Two of them were gold! That's right, the 2 by that card means there were two gold ones. I wasn't sure, so I checked. How awesome is that?
