#2 Finn Balor
Here is an interesting match-up simply because Balor and Reigns have never really been involved together in a proper angle before.
Balor, the man, has been booked pretty strongly but it is his alter ego, the Demon, that has never tasted defeat in the WWE so far.
Of course, it goes without saying that the Big Dog will put that statistic to the test... but storyline-wise, there's always room for good booking when something genuinely has to give.
Reigns has run roughshod over everyone in his path of late. The Undertaker, Braun Strowman, John Cena... the list goes on.
But will he be able to take down the seemingly invulnerable Demon who just can't seem to be beaten?
I, for one, would love to find out.
