What could happen at the Elimination chamber 2018

#4 Undertaker finally challenges John Cena

Undertaker and Cena at WrestleMania needs to happen

So my first prediction was John Cena winning the Elimination Chamber match, but what if WWE has Cena in the Chamber for a different reason. We all know the Elimination Chamber is supposed to set up WrestleMania rivalries, right? WWE can start this dream match like this; Cena is about to eliminate a superstar, and - surprise - Undertaker stops him, starting a rivalry between the two that culminates in a match between the two at WrestleMania. WWE has to plan the rivalry correctly to make it as awesome as it can be.
