#1 The Ascension
There was simply no other choice here. NXT's longest reigning Tag Team Champions and one of the most dominant forces in NXT history simply can't buy a win on the blue brand right now - and it's been like that for quite a long time.
In NXT, The Ascension destroyed everything in their path, including legendary WWE tag team Too Cool and the Lucha Dragons, before eventually losing the titles to the Lucha Dragons one day short of a one-year reign, and then had another rare loss to an impressive pair of Finn Balor and Hideo Itami.
Well, on the main roster, the losses have not been quite so rare. The pair has found themselves getting scraps of TV time alongside Breeze and Fandango in the Fashion Files segments, but their most recent match saw them lose incredibly quickly to Chad Gable and Shelton Benjamin just weeks after suffering a similar fate to the Bludgeon Brothers.
The Ascension would then confront the nWo's Scott Hall, Kevin Nash and X Pac, before being laid out by the APA and the New Age Outlaws. While The Ascension got a win over Billy Gunn and Road Dogg, things quickly went downhill for The Ascension and they've never got anywhere near the level they were at in NXT.
In 2015, The Ascension returned to NXT for one night only to answer the challenge of American Alpha in a match that saw the crowd show their appreciation to the former champs.
If this match showed anything, its that the Ascension could do with a return to NXT, although the tag team division there is even looking pretty stacked right now. The Ascension are probably the most underutilised Superstars on WWE television right now, and I can only hope their luck changes soon - although it doesn't look likely.
