I've been using a Zoroark/Gengar combo, and it's not going to Ubers anytime soon. If fact, it's not even going there at all. Zoroark is fun to use, but 105 speed isn't good enough. The new Fighting and Flying trios, for example, outrun it. It falls to priority, too. Sure, it can hit scizor with flamethrower, but scizor would use Bullet punch on gengar too. Neither of them can really heart Chancy, even with focus blast, which, by the way, is inaccurate. Also, if you want a swords dance+suckerpunch, use absol, for much higher attack and super luck to stack on night slash.
This is not definitely not going to Ubers. In fact, it won't be able to scratch Ubers.People usually fall for it when I do it...If Team Preview didn't exist, Zoroark would be a lot more useful. The jig is pretty much up when the match starts and a smart opponent can easily tell which is the illusion once it attacks.
