Hey! well, the way I see it, its pretty much the same so far.
The market is going to decide the price of every card, but, at least with gold foil cards, the price is set by the amount of power the card has. Usually, a new edition gold foil reward card has 1/4 of the untamed gold foil card, and the price is adjusting to 1/4 too. Sometimes cheaper, something more expensive.
You are missing something important. The amount of reward cards that can still be looted from the chests is huge. Its been two weeks and the price of this cards is really low and there is over 95% left of the total amount of rewards card that can still be found/looted. Even if the price doesn't drop further, you can just found those cards playing the game, so anyone can still raise their power just by doing the daily quests and increasing their rating for the end of season rewards.
