Passage of Persistance should just be get 7 wins and you get the adept. Losses don't hurt in anyway, and you don't have to do any card resetting until you get the adept. Once you get it, you reset and get another adept roll after 7 more wins. This would keep people in the playlist until they get their god roll and make the mode much healthier.

As someone who goes flawless multiple times every week, I think its a great idea. 1 adept for any 7 win card is not going to break the game, its going to get more players into the game mode. More people will farm cards and play the game.
