If I was writing the show, I would have eight guys in the tourney, and every winner in their respective qualifier enters a 4-way Elimination match for the title. The first matches are picked at random.
Match 1: Reigns over Ambrose
Match 2: Owens over Ziggler
Match 3: Batista over Ryback
Match 4: Cesaro over Big E
Survivor Series Style Elimination Title Match:
Reigns
Owens
Batista
Cesaro
Huge shocker as Reigns gets eliminated first when an unknown man runs out and interferes.
Owens is then eliminated by Cesaro.
Batista and Cesaro are the final two, and eventually Cesaro picks up the win and is the new champion.
After the match, Owens is still at ring side, and him and Batista run in the ring and attack a celebrating Cesaro in frustration.
Camera cuts to the back to Reigns walking, where Rene Young stops him and asks who he thinks was the attacker? Just as he is about to talk, he sees a guy in the distance that is dressed like the attacker, he runs up and pulls the guys hoodie off and it is revealed his attacker was Ambrose.
Show ends with Reigns looking at Ambrose like he's seen a ghost.
