#4 The IIconics

The Australian duo of Peyton Royce and Billie Kay have been improving quite a lot ever since their early days in NXT, and they've slowly developed into one of the best heel pairings that Smackdown Live has to offer.
In terms of in-ring work, they fall short of the elite performers in WWE's women's division (Lynch, Charlotte, Asuka), but they can more than hold their own in the ring, and with the genuine heat they can draw, they're a star pairing.
They haven't quite yet hit their best, and the other 3 teams ahead of them on this list have, but expect these two to be competing for the titles shortly after the Elimination Chamber. As an Australian, I'd love to see Kay and Royce continue their rise through the WWE ranks, and as one of the only permanent tag teams in this bout, it makes sense, but unfortunately, we just can't see it happening... yet.
Did a WWE Hall of Famer predict John Cena's heelish ways long ago? More details HERE.
