Leaked information

Note: This leaked cards were shared by XOF.

Here are the list of cards datamined this July. Since a new pack is just recently added, these cards might be rewards from upcoming Duelists or might be even added on Card Trader Rotation.

Here is a list of cards datamined from the game data in early June. Are some of them possible to be added as new cards from the upcoming new pack?

Blue-Eyes Ultimate Dragon will have a summoning animation with Kaiba soon!

New cards are confirmed! Credited to the dataminer, XOF, some new cards were found from the game data. We are not sure how those cards will be added to the game at this point.

The game received an update today. With 14.92MB worth of data download, it came with some AI changes, and datamine has revealed that new cards are added into the game:

Note: Just because these cards are in the game files, does not necessarily mean that they will be obtainable.

In early February, someone was able to datamine and extract the game files. It contains audio files of characters using certain cards, list of cards and icons. While they are in the files, this does not necessarily mean that they will ever be released. Credits goes to the uploader:

Someone uploaded the card images to imgur showing the SRs and URs. Again, just because it is in the game files, it does not mean that they will ever be released. Credits to uploader, link to the source at the top of SR imgur page.

Images showing new cards along with their rarity has started to spread around. These are only rumors with no confirmation if they are real. It is not yet known if they are cards for the next pack or possibly for the KC event.

More pictures and videos have surfaced showing Yami Bakura and Yami Marik. Getting a good glimpse of their dialogues, skills and cards. With the conclusion of Pegasus event, either of the two might come very soon for the next event!

Images have started spreading around showing Mokuba Kaiba, similar to the style used in the game's pictures with different emotions, a battle pose and character selection screen. Could he be the next new obtainable character!?

The other image shows the game's icon list, which also contains information showing that there are XYZ and Synchro icons, a possible confirmation perhaps?. It is only a rumor with no announcement on how long it will come, if it even will be.
