Hi @mano237, I see you calculated the Orbs at a rate of 2500 Dec. I was thinking you are supposed to open it and get the actual value of the cards you got.

The reason why I say this is because I bought the mystery potion and was getting the Brilliant Mystery Charge and others and 1 common card. But before the last day I got an Orb and when I opened it I got a gold card the value of which covered the cost and left me with some profit.
Cheers.
