Okay. A chest challenge. It gives you a starting chest. You open it and you have to use the cards in it  (the cards that are shown in the chest don't give any numbers, just the cards. there is also a chance you get a legendary in the starting chest).

Your account does not recieve the cards until you complete the challenge.

You get more of the cards that you got in the starting chest the more battles you win.
