Our great and powerful leader Molk has requested more reasoning as to why Zoroark should be suspected, so I will post why I think it is suspect worthy :).
First off, I will start this by saying that I don't feel Zoroark is as blatantly broken as a lot of the other things that have gone through the RU suspect process. However, it is also undeniable that Zoroark is an extremely powerful Pokemon. With the Steel nerf and Knock Off buff, Zoroark has gained a ton of power, as not much resists Dark now and since RU has so few Mega Evolutions, few things can take Knock Off well. Zoroark's strong Knock Off in tandem with a powerful STAB Sucker Punch make it a strong Pokemon on its own, and pair that with things like access to Pursuit, a good Speed tier and attacking stats, and a wide movepool with a variety of cool coverage options and set up moves, and you have a Pokemon that is very strong on its own merits. In fact, on these qualities alone, Zoroark would probably easily still be worthy of A rank in the viability thread.
The thing that breaks Zoroark though, is easily the combination of its qualities alongside Illusion. Illusion allows Zoroark to create incredibly skewed mindgames that can very easily put opponents into a terrible position. For example, let's say you have a Slowking out. Your opponent brings out their Meloetta (that you know is Specs), and you know they have a Zoroark on their team. You can either a) hope that this is a Zoroark and go to a Gurdurr that you have b) stay in and hope its a Meloetta c) go to something else that will take a boatload from either, but will hopefully be able to survive the incoming hit. Each possible play you can make is a risky one due to the fact that regardless of what you do, there is a very good chance that you will get trucked by an extremely powerful attack. Meanwhile, the risk your opponent faces is minimal, because regardless of which Pokemon he sent out, there isn't an absolutely terrible consequence. If they have a Zoroark out, all they have to do is Knock Off. If you went to Gurdurr, they still were able to remove Gurdurr's item, severely reducing its bulk, and if they kept Slowking in, they just lost their Slowking. Of course, the downside is that if you had LO, Zoroark is now obvious, but this can even be mitigated by the use of items such as Dread Plate, or the use of LO on the Pokemon you wish to disguise Zoroark as. Similarly, if you sent out Meloetta, if they went to Gurdurr, they lost a crucial Pokemon that stopped Zoroark, while if they stayed in, they still would be forced to take some damage from Meloetta's attack, and you would take a small amount of damage and possibly be burned by Scald.
You can say this is part of the game, and that since prediction is a crucial part of Pokemon, if you guess wrong, you deserve to lose that Pokemon. However, the thing that separates Zoroark from other prediction games is that it is a much more safe prediction game for the person using Zoroark. For example, mispredicting Sucker Punch or Protect can give your opponent a chance to set up things that will threaten your team or cripple your Pokemon with status, which creates a relatively balanced risk / reward. However, if your opponent correctly predicts Zoroark, your position isn't really THAT much worse for much of the time, which is what makes Zoroark such a cancerous Pokemon for RU. Yes, to an extent this sort of mindgame is limited to only the early stages of the game, where Zoroark and much of your Pokemon are stilled unscathed, making the bluff more effective, but against a lot of teams, particular more offensive or balanced ones, those few turns are more than enough time to turn the tide of the game in your favour through the bluff.
tl;dr Zoroark is a relatively low risk, high reward Pokemon that is exceptionally good at creating situations that put opponents in a bad spot with little effort. The ease at which it can lure out and destroy a lot of counters for certain Pokemon through these mindgames makes it a Pokemon that should be looked at through a suspect test at the very least :).
Also Yanmega is just a dumb and should be suspected asap imo. Specs Tinted Lens trucks slower teams that don't have a Registeel, and Registeel is very easy to remove with the help of CB Dugtrio. Registeel can even be worn down with Yanmega itself through repeated Tinted Lens Bug Buzzes, so sometimes Dugtrio support is not even necessary. LO Speed Boost is hard for faster teams to deal with, b/c Yanmega is extremely strong and surprisingly resistant to priority due to its surprisingly decent bulk. Even though its SR weakness sucks majorly, with so many good spinners / defoggers in RU, it's easy to work around, and once Stealth Rock is off the field, it's easy for Yanmega to come in on things like Amoonguss or Virizion and start putting huge amounts of pressure on opponents. It's not even a difficult Pokemon to use, because the Specs set can simply spam its STABs to nuke whatever it wants. Plz let this have a test b/c it is a dumb.
