Collect them all! A mystical organization came to this land and started a business called "House of Cards". Let’s go and find out what’s in the House! 

In the House of Cards, players can obtain Card Cases from the Card Master. Cards can be acquired from the Card Case. You can exchange great rewards after collecting a specified set of cards. Your remaining Cards can be exchanged for Points. Points can be traded for specific Cards. This will allow you to finish your Card sets more efficiently. 

Due to the mysterious nature of the organization, other information is temporarily unclear. Their representatives have stated, "Details of the new content will be released in the coming days!" There will be GREAT Rewards! Stay tuned!
