Zoroark: What is a good battle combination for it?

I am thinking about disguising it as a shedinja for its ability. It will cover almost all of its defenses if the other pokemon think it is an actually shedinja? Its moves will be dark pulse, protect, counter, and night daze. I am not sure about the item for it though. It is hard to get effective items in black because of the gear station. What is a good battle set for shedinja also? I am planning to buy a focus sash with my bp points. I really want to convince that the zoroark is actually a shedinja. Thanks. What other pokemon you think I could disguise zoroark with?
