I was watching King of Trios and thought "Why not, PWG?" I have two names so far: Do You Like Threesomes? or DDT2 (Dynamite Duumvirate Trios Tournament).
A one night tournament, featuring 8 three man teams:
DojoBros (Eddie Edwards, Roderick Strong, and Adam Cole).
Brian Cage and the Young Bucks.
El Generico and the Super Smash Brothers.
Willie Mack, Ricochet, and Rich Swann.
The Briscoe Brothers and Davey Richards.
Kevin Steen, Akira Tozawa, and Michael Elgin.
OI4K (Sami Callihan, Dave Crist, and Jake Crist).
The Gentleman's Club (Chuck Taylor, Orange Cassidy, and Drew Gulak). [PLEASE!]
Standard single elimination bracket. Field of 8, then 4, then the final match.
Alternate teams:
Golden Lovers (Kenny Omega and Kota Ibushi) and Chuck Taylor.
PUMA and Los Luchas.
The Rottweilers (Homicide and Low Ki) and B-Boy.
This could be a two-night event, with the second (or first) night being a supercard of sorts.
