Recovering Lost or Refined Cards
Initial Required Steps
Did you miss some of the cards during your playthrough? Or did you refine some of them to obtain powerful items through the Card Mod ability? Well, fear not; you can still re-obtain these cards once you reach Disc 4 of the game.
There is one card player that you can challenge aboard the Ragnarok to get your cards back, and that’s Princess Diamond Twin (the one on the left) in the main hangar of the ship. The problem is that she and the other CC-Group members will only appear if you have completed the CC-Group side quest.
Refer to the side quest page below for more information, but note that all the required steps for completing this side quest are outlined in the walkthrough section as well:
The Card Club (CC-Group)
Side Quests

There are a number of rare cards you can win from them and you can challenge them to games to retrieve your lost or refined cards.
Assuming you have completed the quest, and then you reach the part of the game where you have access to the Ragnarok and can begin completing side quests, all the CC-Group members will automatically board the ship with you.

So, how do you recover your cards?
The Princess Diamond Twin on the left will have any of the rare cards that you refined, lost in a card game, or neglected/chose not to collect during your travels through the game. You can find her aboard the Ragnarok in the large hangar room, as shown in the screenshot below.

Helpful Hint
Make sure you read through the Queen of Cards guide in the Side Quests section and complete the last steps before proceeding to Disc 4. These steps involve having the Queen of Cards relocate to Shumi Village before the end of Disc 3 and will make it much easier to win cards from Princess Diamond Twin.
Just continue to challenge her to matches until you obtain the cards that you’re looking for.

How do I force her to play the card I need?
Unfortunately, there is a particular order that Princess Diamond Twin will use to play her cards. She will always play the lowest-level rare card that you are missing from your deck first and will not play a higher-level card until after you have won the one she has from her.
This playing order means that you need to slowly work your way through her rare cards until you reach the top. You will need to recover every card you refined, lost, or missed, working your way to the top.
Which cards will she have?
All of them, with no exceptions. The Princess Diamond Twin will have any cards you did not win from a card player along the way, as well as any cards you missed from the Queen of Cards side quest.
I keep losing more cards to her. How can I increase my odds?
Make frequent use of the Save Point in the room at the back of the hanger (the small door on the right). Save after every card that you win so that you don’t accidentally backtrack and end up losing more cards than you had in the first place.
Princess Diamond will use some of the more complex Triple Triad rules, so make sure you read up on how they work in the Advanced Strategy section below:
