Only thing scarier now is zoroark posing as one. Actually a zoroark posing as either this or gengar could be fun.
People get freaked out, try either use ghost move for little damage, or just give up since they are stuck anyways. Then once they figure it out, its to late. Plus, it can pose by using flamethrower to.
Also, since itll be uber, pair it up with wobbuffett! Seriously, that will just about kill anything when put together.
