#1 Should not form - Finn Balor and Bray Wyatt
WWE had often teased the formation of this tag team after the abrupt culmination of their feud on RAW. However, Bray Wyatt later united himself with Matt Hardy as the Deleters of Worlds ruled the RAW tag team division. But, Matt Hardy got injured and Wyatt was written off TV because of no storylines.
On the other side, Finn Balor who was lost in the mix for so long time has finally made his way back to the top and has emerged as the new #1 contender for the Universal Championship. If he is involved in a tag team angle with Bray Wyatt it would be a step back for the extraordinary man who does extraordinary things and so, WWE should refrain from booking this.
Also, Bray Wyatt too deserves to be a part of the singles division and not limit himself as a tag team wrestler.
