One of the challenges with remaking the page is that you have to start over from scratch. If the page is deleted, it's gone. There's no way for you to see the edit history or anything. So you have to go back to basic research. Get to the library. Sit on Google for an afternoon.
Bureaucrats can bring it back. They (and among others, arbitration committee) can access deleted articles, deletion logs etc. as they please. Undelete has its own process.
