20. The Undertaker Vs. Edge (WrestleMania 24)
Edge cemented himself as a major singles star in big part thanks to this match with The Undertaker, the first chapter in an epic rivalry which ended with a brutal showdown in a Hell in a Cell at SummerSlam. The exciting back and fore contest also marked the first time that the Deadman won at WrestleMania by using his Hell's Gate submission, and despite the fact that reliving this match in WWE 2K15 will require paying for DLC to get the R-Rated Superstar, this is an underrated classic it's worth forking out that extra bit of money for.
