- For a comprehensive guide see the side quest Collect 'Em All for complete information and missable cards.
- See Gwent players page for complete list of available players. While not all of them give unique cards, some do give a randomized card that can only be won by playing gwent.
- It's best not to try and do this in a first playthrough so one can focus more on the story first and not have anything spoiled right away.
