Articles with stubs. Stubs are short and insufficient articles. However, just because an article is short doesn't necessarily mean it's a stub. Some articles are just short because of a lack of information available on the subject.
In some cases stubs may include 'untranslated information' such as names, active + passive card skills or even song lyrics. While it is preferable to avoid these things in some cases it is inevitable due to the current size of the community.
(Please note with song lyrics this is more acceptable as both versions are important in this case, it's preferred if you could place any translation's above the japanese version of the lyrics.)
