After 2 cards bugged out I got one you 7 wins and got my adept. Unfortunately I lost my next match after that and it flawed my card so I was locked out of farming adepts. I got 10 wins after 7 to make sure it wasn't just visual and it indeed ruined my card. I wasted 10+ hours on this only for it to randomly fail.

You can run persistence multiple times too. I got 2 adept summoner on 2 separate 7 win tickets with persistence.
