Open the flag adds new features.
To provide the information of the cards in the most reliable way, sets only will be added when it has been released in the English format.
Because of that, the special category has been created https://opentheflag.com/set/o-jp/japanese-cards which have all the cards that have not release in the English format.
And as the category of Japanese cards can be chaotic, the page https://opentheflag.com/es/cards/recent list the cards that recently release.
In addition, other small improvements have also been added, which I hope you like when you see them.
