#3 John Cena vs "The Fiend" Bray Wyatt (Firefly Fun House Match)
With the addition of the Firefly Fun House stipulation to this match, John Cena's match against The Fiend could become a complete cinematic production, with special effects and all. This could be a mini-movie in the middle of WrestleMania, which could steal the entire show. Cena is an actor and will have thrived in this setting.
And Bray Wyatt is an absolute genius, as evidenced by the entire world he has created for himself. There will surely be many entertaining elements in this match which will make it epic and memorable for everyone watching at home. It will probably be a little over-the-top, but having it inside Wyatt's new home makes this a very exciting prospect.
#2 Kevin Owens vs Seth Rollins
Kevin Owens vs Seth Rollins is the one match that has embraced the idea of having it take place at the Performance Center. What started as gang warfare between Owens, Samoa Joe and various allies against Rollins, Murphy, and AOP has ultimately boiled down to a battle between the two former Universal Champions.
The shift in the story has been really smooth, with KO mentioning how symbolic it would be when he finally gets his WrestleMania moment in the same building where he proved his doubters wrong. Without any bells and whistles, he and Rollins going all out for 20 minutes could prove to be one of the highlights of 'Mania.
