2) The Undertaker vs John Cena: Career vs Career match

This match had been a dream match for years but WWE couldn't execute it well at Mania. The Undertaker is well past his prime and it's about time the Phenom hung up his boots.
According to the rumors, Undertaker is set to fight his last match at WrestleMania 35. I think John Cena is the right person to put an end to The Undertaker's legendary career.

We all remember the moment when The Undertaker came up to John Cena and shook his hand for his impressive debut. Since that handshake, John Cena has gone out to be the top guy and achieve major feats in the WWE.
We could witness the same scene at WrestleMania but the other way around. Imagine the intensity and emotion in this match-up. The Career vs Career stipulation match would make sense and also raise the stakes higher.
WWE, as well as the fans, would regret it if this match doesn't get booked. Watching two legends battle it out for their careers is a story we haven't seen in years. This match could be the highlight of the event.
