#5 Angelico & Jack Evans
Angelico and Jack Evans were highly surprising signings to AEW, as they are relatively unknown in the states compared to the rest of the teams on this list, but at Double or Nothing, they flashed greatness. They've been a team for quite some time, but this was their first match together in years, so to see the chemistry return so quickly is very promising for their AEW careers.
There's still a lot of uncertainty regarding AEW and how everything will work going forward, but these guys are amazing talents, and if they can grow as characters and flesh that out, AEW has found themselves a fantastic team. In Mexico, these guys were known as the White Boys from Heaven (Los Gueros del Cielo), and while that heel act is a lot harder to pull off in America, this is a brand new audience for them, and they'll thrive around so many other great teams.
