#3 6-Man Championship
The 6-man tag team Championships are an integral part of other promotions like NJPW and Lucha Underground, and there's a lot of potential for WWE to incorporate them into their programming as well. I mean take for instance AJ Styles, Gallows, and Anderson who could all team together to form The Club.
It is a little strange for Mick Foley to introduce these titles, but then he was known for the '3 faces of Foley'. So, the number 3 is special to him and he could use this as the reason to introduce the title in WWE.

It is clear that the Firefly Fun House is going to be a faction as well. The New Day, when Big E returns could also potentially benefit from these titles.
It's a shame that these titles did not exist back when The Shield and SAnitY were around, but the Undisputed ERA could benefit from them, upon their call up.
