#2 The Undertaker vs Finn Balor (Demon King)
As previously mentioned, The Undertaker will be competing against Bill Goldberg at next week's Super ShowDown special on the WWE Network, which means that "The Deadman" will have wrestled at every single one of WWE's shows in Saudi Arabia. So, with that in mind, it's realistic to expect that he'll be involved in each card going forward until he decides to retire.
One match that WWE fans have been wanting to see for quite some time is Finn Balor, as the "Demon King," against The Undertaker. Most were hoping we'd get it back at WrestleMania, but it clearly wasn't in the cards.
But, WWE probably should book a match like this for a future Saudi show. It'd probably be a good match, as Balor would likely be able to work well with The Undertaker, despite "The Phenom's" obvious limitations. On top of that, it would allow the "Demon King" character to get a notable win over a legendary character, should WWE decide to go in that direction.
