With 25 minutes of television time left, The Shield hit the ring for the night's main event.
Ambrose was on fire to start, taking the fight to both Erick Rowan and Luke Harper and proving himself to be more than just the chihuahua of The Shield. After a brief appearance by Reigns, Ambrose returned to the match and targeted the knee of Harper.
A big boot from Harper brought Ambrose's onslaught to an end.
The Wyatt Family isolated and worked over Ambrose. The crowd tried to will the "Lunatic Fringe" of The Shield back into the bout.
Ambrose dodged a charge from Bray Wyatt and appeared poised to make the hot tag, but he was caught and driven to the mat by the "reborn" Wyatt. A huge clothesline after bouncing off the ropes gave Ambrose the opening to make the hot tag to Cena.
Cena exploded into the match with his trademark comeback, but Rowan planted him with a big shoulder block. Bray Wyatt tagged in and landed a running senton for two. Harper tagged in and delivered a Torture Rack neckbreaker for two.
A missed running senton from Wyatt ignited the babyface comeback, and Cena made the tag to Roman Reigns.
Reigns, a ball of fire, tore through the opposition as the crowd erupted and rose to its feet.
Cena took out Rowan but was a recipient of Sister Abigail. Ambrose dove through the ropes as the action began to break down.
Reigns recovered from a big boot at the hands of Harper to deliver a spear and score the win.
Triple H and Seth Rollins were shown watching from backstage.

Highlights and Quotes
"Did you ever think you would see this? John Cena standing side-by-side with Roman Reigns and Dean Ambrose." -Michael Cole
"The numbers game [is] working against The Shield." -JBL, making absolutely no sense since the presence of Cena negates any numbers advantage The Wyatt Family would have otherwise had
"I think Ambrose's brains miss the Architect." -JBL on The Shield missing Seth Rollins
It is nearly impossible to mess up a six-man tag match in today's WWE thanks to a formula that the company has perfected in booking those bouts. Monday's main event followed said formula, and the product was a very good contest between six of the hottest stars on the roster.
The only issue that could have derailed the match came in its middle portion, which generated heat at the improper time.
After Ambrose had been worked over, he made the hot tag to Cena and started what should have set up the finish. Instead, the match went another eight minutes after Cena found himself isolated like Ambrose before him.
The crowd went silent and did not really pick up again until the tag to Reigns sent the bout to its conclusion.
That one complaint, however, is not enough to soil an otherwise great main event.
The Shield proved the overconfident Triple H wrong thanks to their strong showing and, more importantly, Cena continues to put himself in the crosshairs of The Authority. Fans witnessed it last week when he interrupted Stephanie McMahon, and he has now surely drawn the ire of Triple H by agreeing to team with Ambrose and Reigns.
What that means for the immediate future is a mystery. What is not a mystery is that The Shield should remain a dominant force on Raw if Monday's booking is any indication.
