I used Zoroark a lot in BW1 and have used it in BW2, so I'll jump in regarding it.
Looking at the moves it got, it really doesn't need a full revamp at all. Just mention Trick on Choice sets, mention the new threats (especially Techniloom) and how Zoroark's teammates should be able to take care of them, and it should be good. I haven't tested Low Kick, but judging by the calcs I've done, I honestly don't think it's worth it. It's really only good against Tyranitar. Virtually all the other targets of Low Kick get hit harder by Focus Blast, except for I think Blissey and maybe Chansey as well, but Zoroark isn't beating them regardless (except for Nasty Plot + lots of hazards support). I would say Low Kick should be AC on the All-Out Attacker set at best.
Also, I believe Zoroark should have the Swords Dance set scrapped. I know you wrote the analysis, but that set is honestly the worst set Zoroark can run. Sucker Punch seems nice, but Bisharp has that same niche and one could probably argue that SD Bisharp is better than SD Zoroark (neither are really that good anyway). Plus, with things like Lucario and Terrakion in the metagame, what's the point? However, if you can justify keeping Swords Dance on the analysis, I won't argue with it.
