Zangoose definitely has potential in UU. Having extremely powerful STAB priority I think can be really dangerous in a meta-game full of choice scarfers.
I think it's all-out attacking set will be its most dangerous, especially when you consider how hard it will be to set up. You still hit ghosts and steels and you can still clean up offensive pokemon with a deadly quick attack. I think this ferret here will be a cleaner to watch out for and could bring some interesting change to things like moxie scarfcross which I see will be booming in popularity soon (if it hasn't happened already).
