#3 The New Day (main roster) vs. The Undisputed Era (NXT)

Even if they aren't holding tag team gold, The New Day represents one of the top tag teams on the main roster. The best team in NXT for the better part of the last three years has been Undisputed Era's Kyle O'Reilly and Bobby Fish.
The two squads have always been linked as dream feuds due to the faction aspect of things. Since Cole and Strong would be in singles action, however, it would only make sense for the current NXT Tag Team Champs to battle Kofi Kingston and Big E. Xavier Woods is currently injured, so any faction vs. faction possibility is impossible at the moment.

All four men deliver in big stakes matches and with NXT putting the main roster on notice, this would qualify as that.
Every match increases in importance due to the battle of brands, and even though The Revival or Viking Raiders are Champions, The New Day have been the standard bearer for tag teams for the last five to seven years. The Undisputed Era have been that for the Black and Gold Brand for the last three years.
