Tag Team Broly sounds like a lot of fun actually, with dominance plus paragus/anger he could, in principle, even get to level 2 consistently. He also has utilities in the form of cooler and nappa. I like it! But lets be real here, Ginyu should be in this meta, and will be. If you asked me now I would say Mischievous Ginyu will be an up and coming deck.
As a DB deck, I would not want to play against an oppressive deck that spams unpreventable damage and then ends combat. Imagine him grabbing namek ball 7... he wouldn't even need to filter through his hand anymore.
