Bokor advancement issues

My friend got some issues with Bokor advancement, the quest called hidden card or something which need a boss card, but all his cards were given to his sorcercer through cardbattle,which means he has no cards left. Is there any solutions to solve this problem? I’ve checked that the upcoming quest which has boss card is lv99, that will make him lose tons of class exp. Is the lv50 dun boss rush the only way can solve this? Hes lv 79.

50s dungeon cube contains a card. Maybe. Guess its 10% ?

He should look out for Abomination (guardians graveyard) as well.
