Ranger Mike the difference between Zygarde and other setup up sweepers is that it is much harder to stop it from setting up and sweeping. This is greatly due to a great tier with phazing, so that it itself can not be phazed. Defensive teams fail to be able to status it before it sets up a sub, and can't phaze it before it phazes you. Offensive teams can still take a bit of a hit from Zygarde even if it is unboosted, granted it hits the right Pokemon, and its bulk with Substitute can make it hard to revenge. This is why Zygarde can get to +3 so much easier than something as frail as Lucario, because Zygarde gives itself a multitude of more setup opportunities.
That being said, I still haven't used it or seen it during the retest yet. Togetic is still a legit mon in the tier which shits all over Zygarde. T-Spikes as previously mentioned are good and Infiltrator mons help. Or alternatively we could just chuck an Air Balloon on any random Fairy, don't let the balloon pop and call it a day :^)
(Though my guess is there will be some set diversity)
