In isolation, Limit Regulations cannot define a format. These need to be combined with the contemporary card pool to actually reconstruct a format, which requires release date information via DawnbrandBots/yaml-yugipedia#2

Added OCG Japan link, thanks @larry126

TCG cards not legal in Europe 🙃 https://img.yugioh-card.com/uk/gameplay/detail.php?id=426

Per DawnbrandBots/bastion-bot#324, the UK site is now dead, leaving just the US site at https://www.yugioh-card.com/en/limited/, which means a new way to parse the lists is necessary. Furthermore, the above link for TCG cards not legal in Europe is now dead, instead, seek https://www.yugioh-card.com/eu/play/card-legality/

Alternate version of the TCG list on the LATAM site: https://www.yugioh-card.com/lat-am/limited/index.html

[kevinlul]

New EU list link? https://www.yugioh-card.com/eu/play/forbidden-and-limited-list/

[kevinlul]

Beautiful, the EU site has JSON served from the server, so we no longer need to parse the page body. This contains the database ID too! https://www.yugioh-card.com/eu/_data/fllists/current.json

[kevinlul]

Selecting a list prior to current queries https://www.yugioh-card.com/eu/_data/fllists/61.json. The index number and date of the list is found in https://www.yugioh-card.com/eu/_data/fllists/options.json.

[kevinlul]

Note: the website continues to report the May 17, 2022 list as effective on May 23.

[kevinlul]

Barring any website restructures by Konami again, we won't have to manually update the pointer for TCG Forbidden & Limited Lists now! It should automatically roll over on the effective date.

EDIT: success ee06d6e

OCG lists can be obtained in structured format at URLs of the form https://www.yugioh-card.com/hk/data/forbidden_card_lists/202204.csv

Rush Duel has limit regulations from 2023 onward. These can be found at

• https://www.db.yugioh-card.com/rushdb/forbidden_limited.action
• https://www.konami.com/yugioh/rushduel/howto/limitregulation/ (updates with the upcoming list first)

[kevinlul]

Interesting cardview page for Rush Duel of note: https://www.konami.com/yugioh/rushduel/products/cardview.php?c=orp1-jp034

OCG July 1 has been announced but not reflected on those pages yet https://yu-gi-oh.jp/news_detail.php?page=details&id=1653

[kevinlul]

Reflected on pages a day later

[kevinlul]

Linkross was hit in 2020/04, before it was released in English the following month. Its English name is on the page.

Wisdom-Eye Magician was hit in 2015/10, and its English name is not on the page. It was released in English two months later.

Therefore, converting this list to IDs must rely on the Japanese card names.

[kevinlul]

Full automation has been achieved for OCG, TCG, and Rush Duel. Remaining items:

• create a new yaml-yugi-limit-regulation repository to house most of this work, with a README like the initial issue comment
• transform Yugipedia Master Duel lists to vector JSONs
• transform Yugipedia Duel Links lists to vector JSONs
• potentially provide password-based lflists
• generating full historical card pools based on date per the second issue comment

[kevinlul]

Spinoff successful https://github.com/DawnbrandBots/yaml-yugi-limit-regulation

[kevinlul]

Yugipedia Duel Links lists are incomplete due to outage and not usable

[kevinlul]

Closing in favour of new repository, e.g. DawnbrandBots/yaml-yugi-limit-regulation#8
