#5 Brock Lesnar vs Dean Ambrose: WWE Universal Championship and IC Championship.

To be honest, Dean Ambrose is one of the top heels in WWE. I see him dethroning the IC champion Seth Rollins anytime soon and then may challenge Brock Lesnar for the Universal title. Let me explain, After Roman being on hiatus due to his battle with leukemia, Dean Ambrose seems to be the perfect guy to lead the company. With his recent heel turn, he looks more badass than ever.
Their last match at WrestleMania 32 was a disappointment as it didn't go out how we expected it to be. But things have changed since their last showdown, the lunatic fringe has improved a lot in the ring and looks jacked up. It would be the perfect time for him to channel out the long-lost Jon Moxely and dethrone the Universal champion.
This would not only make him the 1st person to hold both Universal and IC championship but also one of the greatest heels in the history of WWE. He deserves to be in the main event picture as the crowd loves this man. Way to go, Dean, hope this happens.
