How WWE should book the entire WrestleMania 36 card 

Main card match 6

Could this be Undertaker's last WrestleMania match?

Competitors: AJ Styles vs. The Undertaker

Match Type: Singles match

Reasoning: Styles deserves a major WrestleMania match and while facing The Undertaker at WrestleMania may not be the honor it once was it is still another moment to add to his already Hall-of-Fame-worthy career. The story is already written so this one is bound to happen.

Build: Undertaker's storyline with Styles doesn't need to be developed much following the Saudi Arabia event and then Elimination Chamber. All that is necessary is Undertaker to eventually accept the challenge to set up the match at the show of shows.

Match: We've seen The Undertaker can't sustain a high level like he used to so this one should be relatively short. Styles can sell like crazy for UnderTaker's offense before taking control and seeming close to picking up the victory. Having attempted all his typical finishers on the dead man Styles can become frustrated before ultimately Undertaker can sit up and deliver a tombstone for the victory.

Winner: The Undertaker, since Styles doesn't need this win to further his career.
