#5 Xavier Woods and Big E vs. Kevin Owens and Sami Zayn
The other members of the New Day also get a match at Stomping Grounds. Owens' involvement goes back to Fastlane where he was given the title shot instead of Kofi Kingston. After that, he supported the New Day and became a member of the faction while Big E was out with injury.
Right after 'Mania, though, Owens turned on both Kingston and Xavier Woods. He then received another title shot, only this time against Kingston instead of Bryan. Once the turn was made, any time Owens has needed an ally, old friend Sami Zayn has appeared.
Each man has followed members of the New Day when they went to RAW. Zayn has also routinely gone to SmackDown under the wildcard rule in order to help his friend.
When I speak of layers being added to feuds, this is one that has added new ones. Owens' heel turn after befriending the New Day, his constant torment of the trio and the addition of Zayn have all added something new to the feud.
Instead of rehashing the same rhetoric like Lynch and Evans, this build has included a new aspect and old, reliable allies.
