1. A Wrestlemania sized deception

Elias promised the WWE universe that he would deliver the performance of his lifetime at Wrestlemania 34. He did exactly that. Well, almost. He was fresh off of a feud against John Cena and seemingly had no match planned for him going into Wrestlemania. As for John Cena, he 'bought' a ticket to Wrestlemania and sat among the crowd as Undertaker didn't accept his challenge for a match, which meant we were treated to a shot of John Cena sat in the audience at least 3 times during each of the night's opening matches.
After the Charlotte vs Asuka match, a referee ran up to Cena and apparently told him that The Undertaker has arrived in the building. This prompted Cena to sprint full speed up the ramp through gorilla and to backstage. Cena came back out in full gear and waited for Undertaker to come out. The lights went out and out came Elias.
The crowd had been swerved perfectly as Elias came down to the ring and prepared to perform in front of the Wrestlemania crowd. Most of the people booed while some cheered on as Cena simply looked dejected and hopeless.
Cena would leave the ring out of frustration as Elias took center stage and began insulting everyone around him. He went after the crowd, The Undertaker and finally John Cena.
After a few harsh words, Cena snapped and jumped back in the ring. He attacked Elias and laid him out with an Attitude Adjustment to end Elias' night then and there. Although uneventful compared to the other entries on the list, this was Elias' first ever Wrestlemania and boy did he have a great moment. Being part of the John Cena vs Undertaker feud is something newcomers and debutants can only dream of.
