#6 & #5 The Revival
It's quite clear that The Revival, the former RAW, SmackDown, and NXT Tag Team champions are unhappy at how they are being used in WWE, and will most likely leave the company when their contracts expire later this year.

The duo's contract is reportedly set to expire in April 2020 as per Wrestling Observer's Dave Meltzer (via WhatCulture). They filed trademarks for two things associated with them "#FTRKO" and the name of their finisher, Shatter Machine, earlier this year. This is a clear indication that they want to take their likeness elsewhere.
The Revival and AEW's The Young Bucks have talked about facing each other for quite a few years, but they have never had the opportunity to do so because they have not been in the same promotion.
Nick Jackson even spoke about their rivalry in a recent appearance on ESPN West Palm:
“For me, the obvious one whenever people talk about the dream match that never happened would be us and The Revival because I feel like there’s some real-life tension there, and I don’t know if it’s competitive or friendly or whatever it is."
