#3: The Undertaker Vs Shawn Michaels

Okay, so this one is pure fantasy booking, especially given the fact that neither man has expressed any particular interest in being a part of WrestleMania 35 in recent months.
The WWE did tease this though, with the two men coming face to face several times before facing off against one another in a tag-team match at Crown Jewel.
While there is no chance these two men would have been able to replicate the kind of performance they gave on the same stage ten years ago, seeing the two men share a ring one last time would have created an iconic moment and could have brought to an end two of the greatest careers in the history of professional wrestling.
Michaels somewhat tarnished his retirement by returning to the ring in Saudi Arabia, and one last showdown with The Deadman at WrestleMania could have presented him with a chance to put that right again.
