Xerneas has extremely well rounded stats as well as great Special Attack allowing it to become a powerful attacker and is able to further boost its offensive prowess with Fairy Aura and Geomancy. This lets Xerneas serve numerous roles offensively and defensively, making it difficult to switch into. It has many coverage options, but its main alternatives are weaker or lack accuracy I wouldn't go with the drawback, just mention that it has solid high power coverage options. Despite having more options for offensive sets, Xerneas can also utilize its high HP stat paired with its nice defensive typing to opt for more defensive sets or act as a cleric with moves like Aromatherapy and Roar. However, it lacks reliable recovery and relies on Rest to regain health which leaves it vulnerable. the whole thing is still a little messy and there's no switch from pros to cons. the individual defensive set isn't too important to just leave all the cons there, you need to mention that it can be checked by a lot of common steels, fires, and poisonceus pretty hard (although many drop to +2 focus blast) and that it can be pressured by common espeeders which can get right around geo/scarf's speed.

Moves
========
Geomancy raises Xerneas's Special Attack, Speed, and Special Defense two stages, allowing it to sweep a weakened team. Moonblast is the most powerful STAB option that Xerneas has access to and coupled with Fairy Aura and a Geomancy boost it becomes a devastating attack. Focus Blast is Xerneas's main coverage move as it is able to hit Steel-types such as Steel Arceus, Genesect +2 moon blast ohkos genesect, remove this and u have enough examples tho, Jirachi, and Klefki as well as hitting Primal Groudon for more damage. You forgot to mention HP ground as a more reliable option but one that is also way weaker Thunder is able to hit Ho-oh and Lugia hard,and can capitalize on Primal Kyogre switching in. Aromatherapy allows Xerneas to relieve its team from status effects and gives Xerneas an easier time with Klefki and defensive Arceus sets that can wear down Xerneas with Toxic or cripple it with Thunder Wave and Swagger. the order here implies klefki uses toxic and defensive arceus uses twave and swagger, switch either the order of the mons or the moves. Also changing "defensive Arceus sets" to "support Arceus formes" makes it clear that you mean typed arceus and not wallceus, which always runs roar
Set Details
======== fix the spacing on most of these, should be a space in between === and paragraph, and another between paragraph and next section
Maximum Special Attack and a Modest nature ensure that Xerneas deals as much damage as possible. The 52 speed EV's are to outspeed Scarfed Genesect and Scarf Jirachi after using Geomancy. 28 EVs are invested in defense to avoid giving Genesect +1 from Download, and the rest are put in HP to help Xerneas avoid 2HKO's from Extreme Killer Arceus's extremespeed and Earthquake from Banded Ho-oh.
Usage Tips
========
Xerneas has only a single chance to set up, so picking the right time is essential. Normally, setup when pokemon checks like Primal Groudon,Ho-oh,Klefki and Clefable are severely weakened or knocked out is most optimal. Priority users also pose a problem for Xerneas as they can revenge kill it quite easily although priority users need some chip damage in before they can take Xerneas out. that is phrased kinda weird, the point should be that it can be revenged by 1 or more priority users if it takes too much damage while setting up Be wary of how much health Xerneas has and the amount of priority users on the other team before using Geomancy Try to set up on pokemon like Yveltal,Primal Kyogre,and Mega Diancie as you can force them out as well as setting up.
252+ SpA Primal Kyogre Origin Pulse vs. 176 HP / 0 SpD Xerneas in Heavy Rain: 385-454 (88.1 - 103.8%) -- guaranteed OHKO after Stealth Rock
switch this for a new example, say, mega sableye
Team Options
========
Primal Groudon is able to switch into Steel-types and deal with most of Xerneas’s counters like Poison Arceus and Ho-oh. Additionally, Primal Groudon can set up Stealth Rocks for Xerneas so it can sweep more effectively.Primal Groudon also baits in Yveltal and Primal Kyogre which Xerneas can use to setup on. you could give a few other examples for pokemon that use rocks. also Pogre still is not good setup fodder for xern, so still change that to something else Ghost Arceus and Skarmory are able to switch into Mega Rayquaza and Extreme Killer Arceus with ease and are able to cripple them with Will-o-Wisp or phase them out Whirlwind respectively we dont need to know the details of how they handle ray and skarm, the important part is how this actually helps xerneas, which you forgot to mention . Skarmory can also lay down Spikes to restrict switching and force the opponent to defog, giving an opportunity for Xerneas to set up.

Move 4:
Item: Choice Scarf
Ability: Fairy Aura
Nature: Modest
EVs: 72 Def / 252 SpA / 184 Spe edited spread, people felt that we were creeping too much unnecessary stuff. the bulk doesn't actually do anything other than the already mentioned general bulk though, so the reasoning can stay the same
Moves
========
Moonblast is Xerneas’s main attacking move since it deals the most damage because of Fairy Aura and STAB. Focus Blast is able to threaten many Pokemon that resist Moonblast like Primal Groudon,Steel Arceus, and Ferrothorn, however it significantly less reliable against darkrai as it can miss when opting for Sleep Talk . Sleep Talk allows for Xerneas to switch into Darkrai or lead off against Smeargle and is able to ensure the OHKO against both of them extremely reliably and if Moonblast is the only other move it is able to select it every turn. focus blast should be mentioned after sleep talk but specifically say why it's not on the set, as right now it's not quite clear. you should say something similar to "however it is not commonly run because it can make xerneas less reliable in defeating darkrai with sleep talk thanks to its poor accuracy"
Set Details
========
Modest Nature along with full investment to Special Attack allows Xerneas to hit as hard as possible. 224 in speed allows Xerneas to outspeed Darkrai, Ho-oh,and Scarf Kyurem-W. you will always beat hooh and darkrai, those arent really specific benchmarks. it does beat scarf ogre and zek though 32 Defense is invested so that it will no longer give Genesect +1 attack from download as well giving it more bulk.
Usage Tips
========
Since Geomancy is much more common as a Xerneas set remove this point. if anything, bluffing scarf is more effective since you can switch in on things like CBray that expect to die, and I wouldn't mind a bullet point about bluffing scarf in geomancy since it's a risky but effective way to get a free setup, bluffing can be an effective strategy that can lead an early KO. Be wary of what move Xerneas is locked into being locked into sleep talk since many Pokemon can take advantage of it and sweep based on it use it as setup fodder. Xerneas can directly switch into Darkrai and Smeargle since it's running Sleep Talk and KO them the following turn. This set works best as a late-game cleaner, able to blow through the enemy team once all of its counters are knocked out or weakened. Although I think you mean however? otherwise the sentence doesn't make any sense, it is able revenge kill quite well due it its high damage output from Moonblast combined with its nice speed enhanced by Choice Scarf. Despite this set being relatively frail it can switch into some resists resists to what? you mean pokemon it resists? like Yveltal and catch something on the switch with Moonblast. Primal Groudon specifically should be severely weakened or knocked out, as it is able to wall Xerneas quite easily.
Team Options
========
Skarmory is able to switch directly into a +2 Extreme Killer Arceus without fearing Earthquake, as well as being able to phase it out with Whirlwind. Hazard Setters are crucial as they break Lugia’s Multiscale and damage Ho-oh significantly.Primal Groudon and Ground Arceus are able to capitalize on Steel-types switching in if Xerneas is locked into Moonblast. Both Mega Rayquaza and Giratina-O benefit from baiting Groudon out as Mega Rayquaza can threaten Groudon with a 2HKO earthquake or OHKO with Waterfall just say it 2hkos don since its most common set doesn't run those moves. On the other side, Giratina is able to come into any of Primal Groudon's attacks and phaze out Primal Groudon with Roar or Dragon Tail. gira doesn't really benefit from it being out though, since all it can do is phase out pdon. if you just want to say "xerneas needs don checks" that's ok, but benefit is specific phrasing which i dont agree with
[SET]
Name: All-Out-Attacker
Move 1: Moonblast
Move 2: Close Combat
Move 3: Rock Slide
Move 4: Aromatherapy / Sleep Talk
Item: Life Orb
Ability: Fairy Aura
Nature: Rash
EVs: 84 Atk / 240 SpA / 184 Spe
Moves
========
Moonblast is Xerneas’s most powerful move, boosted by both its ability and its Life Orb. Close Combat is able to deal significant damage to Steel-types,Normal Arceus, and Blissey/Chansey, and can be used to weaken Groudon. Rock Slide is able to OHKO Ho-oh and but has very little use against anything else. Aromatherapy is able to get rid of status effects from Klefki and bulkier Arceus sets, and may be used on predicted switches to stop passive damage infliction as well as relieving Xerneas’s team from status. Sleep Talk offers a check to Darkrai as both Close Combat and Moonblast are able to OHKO and Rock Slide is able to break a potential Substitute.
Set Details
========
184 in speed allows Xerneas to outspeed Modest Primal Kyogre, Tank Ho-oh sets and most Primal Groudon sets. The 84 attack EV’s are used for ensuring the OHKO on Maximum HP investment Ho-oh as well as letting Close Combat hit harder. The remaining EV’s are dumped into Special Attack to amplify the power of Moonblast. Life Orb allows Xerneas to hit harder without wasting a turn to setup or getting locked into a move.
Usage Tips
========
Xerneas can bluff Geomancy to ensure the OHKO on Ho-oh Lure in Ho-oh and hitting Steel Arceus for a significant amount of damage when it switches in you already ohko steel arceus with focus blast if it switches in as you geo so I dont get this example. maybe lure in hooh and blissey? Unfortunately, it can only bluff for the first turn as attacks will reveal Life Orb to the opponent. Thanks to its ability it is able do massive damage early game without setting up meaning it can knock out pokemon early game or do massive damage to switch-ins. Due to the lack of HP investment and Life Orb damage constantly wearing it down, Xerneas will not be able to switch into hits, so try to use it to revenge kill or force a switch. When using this set try going for safer options rather than predictions as Xerneas is not locked into an option. idk about this last point, the whole point of the set is to do a lot of damage so if you always click moonblast as they go steel arceus it's gonna fail. if anything I'd suggest you try to catch pokemon pivoting in for one resisted attack before you wear yourself down too much
Team Options
========
Ho-oh is able to switch into most of the Steel-types that check xerneas and retaliate with Sacred Fire. Primal Groudon can also easily deal with Steel-types as well as Ho-oh.Unfortunately,it lacks reliable recovery and can get worn down rather quickly by Steel Arceus’s Earth Power and Mega Rayquaza's Dragon Ascent. this just sounds so random, where did megaray come in in this steel type conversation? and ray checks hooh too. All you have to do is quickly mention steel checks, not take 3 sentences to confuse people Ghost Arceus and Giratina forms can switch into Extreme Speed from Extreme Killer Arceus. Mega Rayquaza is able to take advantage of Aromatherapy and can deal massive damage to Primal Groudon and Steel-types with Earthquake how does aroma let it do that???? If anything a mon with a lum berry is less of a beneficiary of aroma, remove this point. Rock Arceus,Water Arceus and Primal Kyogre are able to capitalize on Ho-oh switching in and are able to force Ho-oh out or 2HKO but hooh doesn't switch in. because it dies to rock slide. I dont get this at all, remove the point i guess. Calm Mind Arceus and Kyogre help take out Xerneas threats like what? be specific with steels and fires while Xerneas is able to get rid of pokemon like Chansey and bulkier Arceus sets that can wall out Calm Mind.
this section is written out really poorly. An example of how I'd change it from being rambling and confusion to just a regular analysis would be like this:
"Fire- and Ground-types like Ho-Oh and Primal Groudon are able to check common Steel-types such as Steel Arceus which can pivot into Xerneas"
A lot of the section also has weird logical leaps, but hopefully I've addressed those. If you ever find yourself taking 3 sentences to say a simple one sentence idea in "fires check steels", that should be a sign that you should try to rewrite it
[SET]
Name: Defensive
Move 1: Moonblast
Move 2: Rest
Move 3: Sleep Talk
Move 4: Aromatherapy / Roar
Item: Leftovers
Ability: Fairy Aura
Nature: Bold
EVs: 252 HP / 252 Def / 4 Spe
Moves
========
Moonblast is Xerneas’s only attacking move on this set as it keeps it from becoming Taunt bait as well as serving as an offensive presence further boosted by Fairy Aura. Rest allows Xerneas to recover lost health as well as shrug off status. Sleep Talk can be used to check Darkrai but it can also be used to attempt to wake itself up with Aromatherapy,phaze out the opponent with Roar or deal damage with Moonblast dont need to list al of this, just say like "Sleep Talk is used to not be completely ineffective while sleeping as well as checking Darkrai" or something like that. at some point being too specific is just annoying. Aromatherapy keeps Xerneas and its teammates from getting worn down by status. Roar is able to get rid of setup sweepers and Substitute Darkrai while also being able to counter check, not counter. it can't switch in, in fact it doesn't exactly check if they just dont set up Geomancy Xerneas sets. It can also do pretty well against Baton Pass teams thanks to Roar phazing out set up sweepers. they dont really have one setup sweeper on BP, maybe "roar eliminating accumulated boosts"? something like that
Set Details
========
Maximum Defense investment along with a Bold nature makes Xerneas as physically bulky as possible. The remaining EV's are put into HP to improve its mixed bulk. this is way overcomplicated, both are just to boost general and physical bulk, you never put things into HP "to increase mixed bulk" Leftovers allow Xerneas to avoid many 3HKOs like what? if you dont know, then you can just say they provide some passive recovery, amplify its bulk further leftovers do not increase bulk, there is no stat boost from running leftovers, and give Xerneas some passive recovery so that it can avoid using Rest. it will still have to use rest
Leftovers provides Xerneas with slight passive recovery.
That is all the sentence needs to say. If you are going to add more, make sure it is actually correct or relevant
Usage Tips
========
Rest leaves Xerneas vulnerable, so using it sparingly is essential, although it does have Sleep Talk which will choose moves at random and can be easily taken advantage of. When opting for Aromatherapy, try using it rather than Rest to get rid of status effects as Rest is easy for your opponents to take advantage of. this sounds really weird, in some cases aroma is better and some cases rest is but I have no real clue when to use either from the usage tip so just remove the point if you can't adequately explain it Xerneas is can easily wall out pokemon like Darkrai and Yveltal xerneas can barely switch into LO oblivion wing from yveltal, diff example maybe. Try to avoid Mega Gengar as it is able to trap and OHKO after Stealth Rocks damage.
Team Options
========
Bulky defensive, not bulky, they all are kinda bulky Arceus Variants and Skarmory are great partners as they can easily switch into Extreme Killer Arceus and phase out opponents when Xerneas opts for Aromatherapy over Roar. Yveltal is able to take on boosted threats such as +2 Extreme Killer Arceus and Mega Rayquaza and OHKO them with Foul Play. Ho-oh can KO Aegislash, Steel Arceus,Ferrothorn, and Skarmory the turn after it switches in. so it can threaten them out? that's typically the way to say it, your way implies that they're staying in on a hooh and also just sounds weird Primal Groudon likes the cleric support and can switch into to Steel-types and Ho-oh but is vulnerable to Steel Arceus’s Earth Power and Ho-oh’s Earthquake. pdon is not a good switch into hooh. you can say it can switch into steel types (and not worry about steel arceus earth power because in general it's a decent steel check) and say something else about hooh checks with like, rock and arceus or something
Other Options
=============
Ingrain on Geomancy sets prevents phasers from forcing Xerneas out after it has already used Geomancy, allowing Xerneas to utilize the boost for significantly longer.Block Xerneas is able to capitalize on bad switches what does bad switches mean? when they switch something that loses to xerneas into geoxern? it's more for trapping weaker mons like support arc formes that they left in to get some chip damage and die so you can geo, rest, wait to wake up, maybe geo 2 more times if they can't hurt you at all like support arc formes can only judgement you for 20% at +2 spdef, and then be healthy and able to sweep with massive boosts. however you describe the set should reflect something like this, but dont spend as much time talking about it as I am here because it's not too relevant and shouldnt warrant 6 lines of explanation as well as trap and use them to set up Geomancy or potentially recover HP with Rest. Substitute can also be run on Geomancy sets, helping Xerneas prevent status and take hard hits without being knocked out again this just sounds weird and overcomplicates something very simple. if they wanted to death fodder something that can't do 25% to a +2 xerneas, now ur harder to revenge kill. simple. Sleep Talk on Geomancy Xerneas can be helpful when switching into Darkrai and Smeargle leads, allowing it to potentially setup or Knock Out the opponent. Three move Scarf sets running Moonblast,Close Combat and Sleep Talk allow Xerneas to hard counter Darkrai,stopping it from choosing moves such as Thunder and Rock Slide remove this sentence that set is dong. Choice Specs Xerneas hits extremely hard without using a setup turn, making it very hard to switch into. Psyshock Arceus you mean psyshock geoxern? is able to get past Poison Arceus and knock out this is redundant
you can mention grass knot on AoA xern if neither aroma or stalk seem too attractive since it can 2hko pdon
Checks and Counters
===================
**Steel-Types**: Steel-types are able to switch into Xerneas's STAB Moonblast.why does that deserve its own sentence e.e Mega Scizor is able to switch in on Xerneas and 2HKO with bullet punch priority scizor is especially notable because it can easily revenge geoxern and you dont even mention that. if anything gets a specific sentence for it, there has to be something important. Bronzong easily switches into any attacks and coverage that Xerneas has and is able to 2HKO with Gyro Ball and capitalize after Geomancy similarly, bronzong is the best xerneas counter in the game but I just see very generic sentences that dont really tell me much. Steel Arceus,Genesect and Jirachi are able to switch into Moonblast as well as revenge kill quite effectively specifically on scarf or All Out Attacker sets. you mean xerneas's scarf or AoA sets? this implies the steel types are running scarf or AoA sets
**Ho-oh and Primal Groudon**: Primal Groudon and Ho-oh are the most offensive Xerneas switch-ins and can knock out Xerneas with little prior damage. Ho-oh's typing resists Xerneas’s STAB and main coverage options, and can heal off damage with Recover and Regenerator or KO Xerneas. Primal Groudon is able to both switch into and knock out Xerneas or phase it out with Roar after it has used Geomancy. both can actually counter geoxern and that isn't really mentioned
**Priority Users**: Priority users need slightly more prior damage in order to ensure KO's. Extreme Killer Arceus, and Mega Rayquaza are able to inflict the most damage with Extreme Speed and revenge kill Xerneas once it's been worn down. Xerneas can still live if it is untouched beforehand however; it can easily be overwhelmed by multiple priority priority users on a single team.
**Lugia**: Lugia is a very solid Xerneas check as it is able to come in after something has been knocked out and take Moonblast easily with Multiscale even after Geomancy and phaze it out with Whirlwind, or wear Xerneas down with Toxic and stall it out.
**Poison Arceus**: Poison Arceus resists both Xerneas's STAB and main coverage move, Focus Blast,and can easily knock out Xerneas with Poison Jab as well as being able to switch into all of Xerneas's sets and can use Xerneas to set up. Poison Arceus can also use the chance to set up against Xerneas; however, it should be extremely wary of coverage moves like Hidden Power Ground and Psyshock as they can deal massive damage. you mention that it can use xern for setup fodder twice, when it's not even a point I'd make in the first place
