I really like the idea of having an established tag team in the group, and these guys would also be fairly cheap hires.
Just now brainstorming the beginning of a new save, but I was considering splitting Krissy and Brandon as manager/client and thinking she could fit since she's got several "used to date" worker relationships.
Wow, ton of ideas! Crippler seems like a great choice for Envy...."What about me? What about The Crippler?" Mainstream could work as a nice tag with DeSousa, and also the "usurper" to Greed's leadership when the group needs to be shaken up. Also like the idea of using Hellion in the place of SoVen (might not be ready for a callup yet anyway).
Big thanks to all three of you for the ideas!
