#6 A.J. Styles and Seth Rollins battle in a slugfest as the final two in the Royal Rumble match

Now coming towards the end of the Royal Rumble match with A.J. Styles, Drew Mcintyre, Lars Sullivan, and Seth Rollins working as the Final Four at Chase Field. With Lars Sullivan being presented as such a legitimate threat, the Royal Rumble psychology could align Mcintyre, Seth Rollins, and A.J. Styles to eliminate Sullivan out of the picture.
This would be an ideal way for Sullivan to be eliminated whilst presenting him efficiently, which would eventually lead to Mcintyre, Rollins, and Styles slugging it out as the Final three.
There's no better way to end this special bout than keeping the Architect and the Phenomenal One as the final two participants to determine the one who gets the golden opportunity to headline the Grandest Stage of Them All.
Considering the ovation this would receive, the Game could creatively book this ending and catapult both the superstars whilst making them tear each other apart to grab the brass ring.
A hypothetical situation where the Phenomenal One is all bruised up after going to war with Daniel Bryan, this would give a determined Seth Rollins the opportunity to take advantage of the situation and slow Styles down and eventually eliminate him.
While I would like to see the Phenomenal One headline WrestleMania one day, I genuinely believe that it is time for Seth Rollins to burn it down and be the Beast Slayer.
