#2 The Young Bucks

Like Omega, The Young Bucks, brothers Matt and Nick Jackson, were also a part of the WWE (even parodied as DX) appearing on TV in ECW, while Matt even wrestled Big Show when he was hired as a jobber by the WWE.
The Young Bucks are a fantastic tag team who have wowed audiences around the world in NJPW and ROH, to name a few, while also featuring in TNA.
One wrong move ruined his entire WWE career - Watch Now!
One of the most successful tag teams in NJPW, the seven-time IWGP Junior Heavyweight Tag Team Champions have carved a niche for themselves, while also creating a huge brand for themselves.
The duo's contracts is also rumoured to expire in January 2019, and they could also perhaps make the switch to the WWE (as they have been teasing on social media; but it could also be a great work!), perhaps debuting at the Royal Rumble.
Their addition to the main roster would add some much-needed impetus to the tag division, especially on RAW, which has been stale despite the likes of Rollins-Ambrose and Ziggler-McIntyre holding the belts.
