Zoroark's natural element of surprise allows you to get up a free Nasty Plot when they realize that the Infernape they just Psychic'd isn't an Infernape at all. From there, just use Night Burst or Dark Pulse to kick some serious butt. Dark Pulse has more accuracy and a flinch chance, but Night Burst has slightly more power and a surprisingly useful chance for an Accuracy drop. Extrasensory provides coverage against Fighting types that might come in on your STAB move. Focus Blast hist Steels and opposing Dark types and is powerful, but has infamously bad accuracy. Flamethrower decimates Steels with reliable accuracy and hits most Dark types neutrally, but sadly, it makes you a sitting duck against Tyranitar.
What do you mean it's not awesome?!
