[Justice] Phantom

But does anyone know if a Phantom can steal Zakum/Pianus's super w./m. def up and just take 1s?

The skill description indicates that you get a particular buff based on the type of monster buff stolen. You don't get the exact same buff the monster had (necessarily). Have we confirmed that stealing a boss buff removes it from the mob in question? That'd be the real holy grail.

And folks, HS works solo now. 70-120 at least, your third job active skill is HS.
