How it will work
For 50 relics you can buy a random golden card every weekend. Not a good price you will say… But: The chance is exactly the same for every card, be it common or legendary. And the card is the same for every player at this weekend. For instance, if you invest 50 relics and get Seelenreisser from the black market, you might tell your friend, cause he will get the very same card this weekend! Or you might not tell him, it’s up to you 😉
What do you think, will you give the black market a visit from time to time?
