An Old Card Album (AKA 'OCA') is a consumable item that gives one random non-MvP card.
Dark Priest Card
Contrary to popular belief, you can no longer obtain a Dark Priest Card from OCA. Gravity has removed the card from the OCA list.
Although you can find it in ExperienceRO's database, there is no way to obtain it. Even RMS removed it from their OCA List.
