I think Cresselia would be an excellent pokemon to go undercover as.
Or even Metagross. I think anything would probably work that doesn't give itself away on the switch in.
Don't worry about feigning resists or abilities (well, Intimidate maybe) and just play it as if it were just a normal pokemon. Remember, they have to guess that it's Zoroark, not you.
For a non-lead, always make sure that Stealth Rock damage is taken into consideration, or spin it away. Feign a spinner like Tentacruel, watch em switch to Rotom-A and eat a Crunch/Dark Pulse. So many options...~babble~
