Wrestlers who recovered from falling right down the card, or elevated from nothing?

Due to Drew McIntyre's initial push and slip down the card, I was just wondering if there has ever been anyone who has fell right down the card and recovered from it?

I'm talking, Drew as an example, debuting or making their way to the top of the shows and being in the upper leagues or even main event, and then falling all the way down to something as little as appearing only on House shows, to actually managing to get back onto TV and then fighting their way back to the top.

I'm sure there are a lot, but at the moment I can't think of any and wondering if anybody else can?
