Forum:Why aren't there pages for certain deck types?

Yea, why aren't there pages for deck types that are mentioned on other pages? I can see there are many reasons not to make a page for every deck type(Even though, isn't that one of the things this wiki is made to archive?), but I don't understand why there aren't pages for some deck types that are mentioned on pages. If they are important enough to be mentioned in other articles shouldn't they have their own article? Is there some sort of discussion that must take place for a new page to be added on a deck type, or is it just a matter of someone forgetting to make the article?
