Overview
########
Zorua is a unique Pokemon in LC thanks to its ability, Illusion, which makes can trick the opponent think that into thinking it's another Pokemon, allowing it to not be hit by super effective moves. Zorua also has decent Attack and Special Attack stats, and with access to both Swords Dance and Nasty Plot, (AC) it can boost its stats to hit even harder. (AP) ; (RSC) it It also has a high Speed stat, (AC) which allows it to hit the 17 Speed tier and outspeed Pokemon such as Pawniard. However, Zorua is really very frail, and its Dark typing makes it weak to the common many Fighting-types in LC. Its shallow movepool leaves it walled by Fairy-type Pokémon Pokemon (no accent), which makes means it need needs a lot of team support to help deal with these threats. (AP) , (RC) but However, thanks to Illusion, it Zorua can avoid Fighting- and Fairy-type attacks if it copies a Poison-type Pokémon Pokemon.

Moves
========
Nasty Plot boosts Zorua's otherwise mediocre Special Attack, allowing it to sweep through teams if its counters are have been worn down. Knock Off can be used instead of Nasty Plot, (AC) as Zorua won't always have the opportunity to set up. (You still didn't mention what Knock Off does) Dark Pulse is Zorua's main STAB move, though Night Daze can be used too, (AC) as it has a 40% chance to lower the opponent's accuracy. Extrasensory is its Zorua's only option to to hurt Fighting-types that would otherwise wall Zorua instead. U-turn is also another option to hurt Dark-types and gain offensive momentum, (AC) while ; (RSC) Hidden Power Fighting can be used instead to deal with Dark-types, notably Pawniard, that might be a problem.
Set Details
========
This set uses Life Orb as an item to help Zorua deal more damage, and with maximum EVs investment and positive nature, it hits 17 Speed with a positive nature, which allows it to outspeed Pokémon Pokemon such as Pawniard; (RSC) it also gets 17 Special Attack. (Unless it hitting 17 Special Attack is especially important, there's no need to mention it.) 0 HP IVs are used to make Life Orb recoil deal only one HP.
Usage Tips
========
Zorua uses Illusion to keep super effective moves away; it mainly disguises itself as a Poison-type to keep Fairy-, Fighting-, and Bug-type attacks away and trick the opponent into using Psychic-type attacks. If you're Zorua is using Nasty Plot, it's preferable to not set up with Zorua until its checks and counters are down have been removed so that it can sweep without fearing the fear of being revenge killed. (AP) ; (RSC) Instead, try to set up when a Pokémon Pokemon is forced out by whatever Zorua is disguised by you should take the opportunity to set up with Nasty Plot. Also, it's preferred that Zorua is at full health, as a difference in HP between it and the Pokémon Pokemon it's copying might make cause the opponent know that it's actually Zorua.
Team Options
========
Entry hazard support from Pokemon such as Dwebble and Tirtouga help can assist Zorua sweep sweeping. Another great example is Trubbish, as it's able to set up Spikes and also deal with Fairy- and Fighting-types; in return, Zorua deals with Psychic-types that threaten Trubbish. Hazard removers such as Drilbur and Archen are also important, as the damage received from Stealth Rock entry hazards might ruin Illusion. Fletchling and other Flying-type Pokemon are also great teammates, (AC) as they help take down Fighting-types. Pokemon that can take down Fairy-types that Zorua cannot deal with are also necessary; examples include Magnemite, Pawniard and Gastly. (You talked about how important is was to disguise Zorua as a Poison-type earlier in your analysis, and yet you don't have a section where you specifically mention good Poison-types for Zorua to disguise itself as? I'd definitely add one.)
Other Options
########
A Swords Dance set with Knock Off, Sucker Punch, and U-turn can also be used. Agility is an option to double Zorua's Speed, (AC) but it's not really ideal because Zorua lacks raw power to sweep without boosts in its Attack or Special Attack stat, and it also has access to priority in Sucker Punch. Zorua can use Taunt, but most of its counters don't really have a problem with being Taunted, (AC) as they usually choose to attack and do huge amounts of damage because of its target Zorua's low defenses. Memento can be used to give the opportunity for a set up setup sweeper to come in and set up safely. Pursuit is also an option to trap some Pokemon like such as Gastly while disguising as a Pokemon that threatens the foe. Zorua can also use a Choice Scarf set with Trick.
Checks and Counters
########
**Fighting-types**: Fighting-types can deal with Zorua unless it has Extrasensory. (AP) ; (RSC) priority Priority Mach Punch and Vacuum Wave from Timburr and Croagunk, respectively, deal a lot of damage to it Zorua. Scraggy is also a nice counter as it's immune to Extrasensory.
**Fairy-types**: Fairy-types such as Spritzee and Snubull can wall Zorua and take it down with Moonblast and Play Rough, respectively.
**Dark-types**: Zorua cannot deal with beat Dark-type Pokemons like Pokemon such as Vullaby that can tank its attacks. Pawniard also deals with Zorua as long as it doesn't carry Hidden Power Fighting.
**Choice Scarf users Users and Faster Pokemon:(RColon)**: Choice Scarf users can easily revenge kill Zorua because of its low defenses; faster Pokémon Pokemon can also play the same role. (Maybe give some examples, or mention how some have to be wary of Sucker Punch?)
