You are right, a miscalculation.

Should have kept the prices the same. Doubt any ordinary Joe will go for the prepurchase 21$.

Worse part is when they nerf a card the whole deck is ruined not only that card. Like lunar was nerfed that kind of ruined the whole mage deck. Sure I can disenchant my Lunar dust but what about the other cards I created.

I think you mean 17 packs, 16 + 1 Golden pack.

Dont get me wrong it looks like fun and I want to buy the adventure, but 12 packs for 2100 Gold or wait for the second release and buy 21 packs. Since I cant afford the money on this game I have no option but to wait. Maybe in the future they might make it more worth our while like a legendary per adventure. Hard to keep up with this game if you dont have the money to spend.

Maybe if it was golden it would be worth. This way you can always disenchant it.
