Vermyn N can be good if used Offensivly. 7 Damage is nice. Also the High DR should stay.
I like Shann and Blaaster too.
So, I'd actually use that unless you feel like changing.
Shann to Shogunn
Juicy Lord to Chlora
That'd be 4 four stars, a Three, and 3 twos.
Vermyn N is definitely needed for a mono Bangers deck for survivor.
the dual threat is superb for him.
i would use shann of course
Naykee (i would only use him because you need some sort of atk manipulation in survivor by Juicy Lord is also an option)
Bennie (although i recommend Massiv as well)
gl to you
