I made it to Gold 1 again, so I was pretty happy with that. But I didn't really get much good in my rewards.
The gold card is always nice, but I've noticed a big difference in running potions and not. My gold and legendary openings have dropped off significantly since my potions ran out. I'm still debating the value of potions vs. return. I'm very curious how the release of Untamed will affect the value of existing cards. But I think ultimately the only thing that's going to make this game (and the value of the cards) take off is getting more players somehow.
