I think it was the authors of pain. They will be repackaged upon debut with darker gimmicks and have an enforcer gimmick for a new character called The Undershaker. This is actually No Way Jose but he's in darker clothes and has dreads and an evil goatee. They will sacrifice Breezango and eventually recruit them into The Ministry of Dancers

Then Sanity will debut in a six man tag against The Authors of Pain and The Undershaker and the new guys will have the upper hand until The Fashion Police gets involved and they beat them down brutally. The Undershaker hangs Eric Young off the ring with a noose and chokes him out

Next week, breezango are facing Zack Ryder and Sami Zayn in a falls count anywhere and all of a sudden, Sanity interfere and help the fashion police win and join The Ministry of Dancers.

This will lead up to a storyline where The Ministry of Dancers try taking over the WWE and forcing Brie Bella to date The Undershaker

The shadow from one of the guys during the PPV definitely had a big shadow. So unless WWE threw a really shitty, unexplainable red herring at us, it's either Harper and Rowan or SAnitY.

EDIT: Sorry, I just read the first sentence and didn't notice who posted the topic before responding.

I think it was The Bromans
