#3 AJ Styles
AJ Styles is one of the best wrestlers to ever step foot in a WWE ring. He is the current WWE Champion and is a part of the Smackdown Roster.
As we all know, Smackdown Live is the house that AJ Styles built. But The Undertaker was one of the most dominant stars on Smackdown from 2002 to 2010. Both of these superstars have tremendously contributed to the success of Smackdown and the WWE.
Styles is the current WWE champion, but it is unlikely that he will stay champion till Wrestlemania 35. His current reign as WWE champion just completed one year and his reign as champion might soon be over. So it is perfect for Styles to face the Undertaker at Wrestlemania 35.
WWE can promote the match as the 'Phenom vs Phenomenal' match just like they promoted the match between Lesnar and CM Punk as the 'Beast vs Best' match.
Both of the superstars have great promo skills and when they will confront each other it will definitely be a sight to behold. A match between them will definitely tear the house down and this match will also help Styles to further solidify his legacy.
'The Phenom' vs 'The Phenomenal One' will be an outstanding rivalry if it will be booked properly.
