[OVERVIEW]
The most powerful and versatile Fairy-type available, Xerneas is capable of pulling off a variety of tricks and is able to do them well. The Geomancy set shapes the metagame around it, being one of the most dangerous albeit prepared-for sets in the tier. Although Xerneas's raw stats aren't particularly impressive in a single aspect, its defensive stats are solid and backed up by an above average HP stat, and its base 99 Speed allows Xerneas to outspeed several relevant threats in the Ubers tier. While base 131 Special Attack is good, its not particularly high without a Special Attack boost or a Life Orb, as many other threats in the Ubers tier such as Mewtwo and Kyogre have higher raw offenses and Xerneas's coverage moves aren't boosted by Fairy Aura. Xerneas's ability functions as a buffed Life Orb for Moonblast without forfeiting the item slot or taking recoil, making offensive sets more potent and allowing defensive sets to hit hard without investment. Mono-Fairy typing is good defensively, granting only a few weaknesses along with a handy immunity to the Dragon type. Xerneas is capable of running many coverage moves, although most of these are either weak or have an accuracy drawback. It does have some good support moves such as Aromatherapy and Roar, but the lack of instant recovery means it has to run Rest on a defensive set. Furthermore, Xerneas is afflicted by all entry hazards and by all nonvolatile status, somewhat reducing its defensive synergy. Some Xerneas sets are vulnerable to Shadow Tag Mega Gengar, and Xerneas is impacted by the fact that the most common Pokemon in the tier, Primal Groudon, resists Moonblast.

Moves
========
Geomancy turns Xerneas into a fast, powerful, and specially bulky setup sweeper at the cost of the item slot. Moonblast is the best Fairy-type move available to Xerneas and, when combined with the +2 Special Attack boost from Geomancy, STAB, and Fairy Aura, allows Xerneas to hit very hard. Thunder hits Ho-Oh, Primal Kyogre, Lugia, and most Steel-types. Thunder is always used over Thunderbolt because a super effective Thunderbolt is weaker than a Fairy Aura-boosted STAB Moonblast and thus not worth running. Aromatherapy is an alternate option to Thunder that trades hitting the aforementioned threats for the ability to support teammates in a pinch or remove status from Xerneas. Focus Blast rounds out Xerneas's coverage by hitting Primal Groudon, Ferrothorn, and some other Steel-types. Hidden Power Ground is an alternate, perfectly accurate coverage move that hits Primal Groudon just as hard as Focus Blast and hits Steel-types such as Klefki harder than Moonblast at the cost of not being able to hit Ferrothorn and a few threats such as Steel Arceus as hard as Focus Blast.
Hidden Power Fire can be used to hit Ferrothorn just as hard as Focus Blast without accuracy issues while it also hits Mega Scizor very well and still handles Steel-types in general. Substitute is an option that allows Xerneas to avoid being hit with status. This is particularly useful against Pokemon that rely on Thunder Wave to halt a Xerneas sweep, as Xerneas can set up a Substitute on the turn the foe uses Thunder Wave or as Klefki comes in. It is also an effective move against some defensive Pokemon such as Aegislash and Blissey.
Set Details
========
Maximum Special Attack investment ensures that Xerneas hits as hard as possible once boosted so that it can effectively sweep; the most prominent benchmark is a guaranteed OHKO on maximum HP Arceus formes after Stealth Rock. 44 Speed EVs are used so that Xerneas is faster than Choice Scarf Genesect after a Geomancy boost. 28 Defense EVs give Genesect a Special Attack boost with Download and, when combined with the 184 HP EVs, they allow Xerneas to always survive a +2 standard Extreme Killer Arceus's Extreme Speed after Stealth Rock. A spread of 56 HP / 156 Def / 252 SpA / 44 Spe with a Modest nature can always survive +1 Adamant Mega Salamence's Return and gives Xerneas more physical bulk in general; however, it's 2HKOed by Life Orb Yveltal's Oblivion Wing much more often. A Power Herb allows Xerneas to set up Geomancy in a single turn.
Usage Tips
========
Unlike other setup sweepers such as Dragon Dance Mega Salamence and Extreme Killer Arceus, Geomancy Xerneas can only set up once because a Power Herb is a single-use item. This makes choosing when to set up perhaps the most important aspect of using Geomancy Xerneas. Usually it is not a good idea to set up when the opponent still has healthy Xerneas checks, because this gives up your one opportunity to sweep for little to gain. There are exceptions, however; Xerneas can set up in order to tear down a Pokemon such as Primal Groudon to pave a way for another Pokemon to sweep or can be used to force a trade with a troublesome Pokemon such as Klefki. In general, though, it is best not to set up Geomancy Xerneas until its checks have been eliminated or, more realistically, damaged enough to be blown past. The methods in which an offensive team checks Geomancy Xerneas are usually a different beast entirely. Such teams usually focus on a combination of damaging Xerneas on its setup turn along with the employment of a revenge killer such as Extreme Killer Arceus. Unlike defensive checks, offensive checks cannot be blown past in the same way; it is irrelevant how damaged the opponent's Extreme Killer Arceus or Mega Scizor is because they have priority over Xerneas. This means that unless you benefit from the trade that will occur by setting up Xerneas while a revenge killer is alive, it is best not to set up or, in a rare scenario, attempt to set up in a situation where you won't be damaged on the setup turn so much that you can be revenge killed.
In both cases of knowing when to set up, you must be acquainted with what amount of damage Geomancy Xerneas is capable of taking and dealing. If the opponent has a Rayquaza with Extreme Speed in the back, determine how much you can afford to let Xerneas take when setting up. Similarly, know how much you need to have chipped away at the opposing Lugia before you are ready to sweep. Many teams use Primal Groudon as a check to Geomancy Xerneas, and this can be capitalized upon due to its lack of recovery. Rather than setting up Xerneas right away when a Primal Groudon switch-in is obvious, smack it with Moonblast as it comes in. Switch out, and repeat this the next time you can get Xerneas in for free; after taking two Moonblasts, even specially defensive Primal Groudon can be broken after setting up. Note that Geomancy Xerneas doesn't really want to switch into anything because it is most deadly as a sweeper when at full health. This set can afford to switch into offensive Yveltal; however, Oblivion Wing deals significant damage. Xerneas can be aggressively double switched with in order to break down its checks via offensive partners that perform well against said checks. Because Geomancy Xerneas is good at forcing switches, especially against defensive teams, this provides opportunities to bring in other offensive threats that can start blowing holes in the opposing defensive build. Xerneas has an immunity to Dragon-type moves, and although they are not extremely common, bringing Xerneas in on a predicted Draco Meteor is one of the better methods of getting it into play. In some matchups, a Geomancy Xerneas sweep will be difficult or not worth it; in such scenarios Xerneas can be used more as a team player to aggressively pivot against Pokemon such as Yveltal and Giratina-O.
Team Options
========
Primal Groudon is able to threaten virtually every Xerneas check that isn't Lugia, making it an excellent offensive partner for Geomancy Xerneas. Extreme Killer Arceus is a setup sweeper that pairs well with Geomancy Xerneas for offensive teams due to how they pressure similar checks. Ghost Arceus is a great partner, as Xerneas can threaten Yveltal while Ghost Arceus is immune to Extreme Speed and can break down several Xerneas checks with Will-O-Wisp or Judgment. Mega Salamence provides a method of threatening Primal Groudon and Ho-Oh, which are two of the most common checks to Geomancy Xerneas, and it also performs well against Extreme Killer Arceus; Refresh variants can also provide an excellent switch-in to Sacred Fire from Ho-Oh. Mega Gengar can be used to trap and eliminate several checks to Geomancy Xerneas or force them to trade with Destiny Bond, making it much easier for Xerneas to sweep later on. Ground Arceus plows through almost all defensive Xerneas checks and provides an immunity to Thunder Wave. Darkrai can pressure the defensive backbone of an opposing team, as it is a very difficult Pokemon to switch into, making it easier for Xerneas to break down the foe. Mewtwo formes greatly appreciate Xerneas's ability to check Yveltal and in return can stallbreak against defensive builds that Xerneas may struggle with. Life Orb Zekrom effectively pressures Ho-Oh and can beat down Klefki and Primal Groudon with Bolt Strike and Draco Meteor, respectively. Giratina-O appreciates Xerneas checking Yveltal, can perform well against Primal Groudon, and offers an immunity to Fake Out and Extreme Speed. Lastly, setters of entry hazards make ensuring a Geomancy Xerneas sweep much easier, as Stealth Rock can ensure the KO on Lugia and Ho-Oh while Spikes can break down Primal Groudon and Steel-types.

[SET COMMENTS]
Moves
========
Moonblast is the primary attacking move for this set, as it's not a particularly bad move to be locked into and is the strongest move available for Choice Scarf Xerneas. It also has a good chance at lowering the foe's Special Attack one stage, which can be handy against special attackers that switch into Choice Scarf Xerneas. Focus Blast can hit most targets that resist Moonblast, such as Primal Groudon and Steel-types not named Aegislash. Sleep Talk allows Xerneas to directly switch into Darkrai's Dark Void and potentially knock it out before it can attack again. It also sees use against the rare Spore Smeargle. Aromatherapy allows Xerneas to provide emergency cleric support for its teammates. Thunder allows Xerneas to hit Ho-Oh, Primal Kyogre, and Lugia a bit harder. Grass Knot can hit Primal Groudon just as hard as Focus Blast without the risk of a miss while also hitting Primal Kyogre and a few other threats such as Ground Arceus, Rock Arceus, and Water Arceus. Rock Slide hits Ho-Oh much harder than Thunder, but it doesn't hit anything else.
Set Details
========
252 Special Attack EVs with a Modest nature are used to maximize the damage output of Moonblast, better allowing Xerneas to revenge kill weakened threats and chip away at Pokemon such as Primal Groudon. 224 Speed EVs are used to outspeed +1 Rayquaza and Kyurem-W. 32 EVs are slotted to Defense to ensure that Genesect gets a Special Attack boost from Download. The set revolves around the use of a Choice Scarf, which allows Xerneas to revenge kill threats such as Darkrai, Mewtwo, Shaymin-S, Deoxys-A, and weakened Arceus formes. Running 252 Speed EVs is an option that allows Choice Scarf Xerneas to outspeed maximum Speed Deoxys-A and tie with opposing 252 Speed Choice Scarf Xerneas. If using Rock Slide, the 32 Defense EVs can be invested into Attack, which slightly increases the damage output of Rock Slide but fails to meet a specific benchmark.
Usage Tips
========
Capitalize on the ability to bluff a Geomancy set; this can allow a free KO on a Pokemon that assumed it was faster. One of this set's main draws is that it performs better against Darkrai than most Pokemon, although you mustn't switch it directly into an obvious Sludge Bomb or into Dark Void if you aren't running Sleep Talk. Be very aware of what move Xerneas is being locked into; for example, if your team is in a situation where it cannot afford to allow Mega Salamence to set up, do not KO a Pokemon with a move that is not Moonblast. Aromatherapy is best used on turns where you are certain that the opponent is going to switch because Xerneas is threatening one of their crucial Pokemon. However, if they are going to a Pokemon such as Double Dance Primal Groudon, make sure you can afford to give it one free turn. Prediction is unfortunately a large part of using this set. When considering what Pokemon is going to come in, consider other factors as well, such as risk associated with getting locked into this move against one possible switch-in versus the potential benefit to be gained by predicting correctly.
Team Options
========
Choice Scarf Xerneas is generally a pretty self-reliant set, although a few partners can offer offensive and defensive synergy. Primal Groudon is an effective partner that can deal significant damage to a wide range of typical Choice Scarf Xerneas switch-ins. Furthermore, it benefits from Xerneas's ability to threaten Darkrai and Yveltal. Mega Salamence can provide Choice Scarf Xerneas with a method of threatening Primal Groudon and Ho-Oh, both of which are commonly used to tank Moonblasts. Mega Gengar can eliminate or force a trade with a troublesome Pokemon so that Moonblast spam becomes much more potent. Ghost Arceus and Giratina-O greatly benefit from Xerneas's ability to check Darkrai and Yveltal, and Ghost Arceus performs well against Mega Gengar and can burn troublesome Steel-types with Will-O-Wisp. Latias and Latios also benefit from Xerneas's ability to check Dark-types, and they can offer anti-entry hazard support and threaten Primal Groudon. Ground Arceus is capable of breaking down most checks to Choice Scarf Xerneas, while Rock Arceus can provide a very stable switch-in for Ho-Oh.

Moves
========
Moonblast hits especially hard with both Fairy Aura and a Life Orb, and it is the strongest STAB move available to Xerneas. Aromatherapy allows Xerneas to provide support to teammates, and it can be used on the turn Xerneas forces an opposing Pokemon out. Thunder hits Ho-Oh, Primal Kyogre, and Lugia hard and also hits a few Pokemon that resist Moonblast and resist or are immune to Fighting-ype coverage moves, such as Aegislash and Poison Arceus. Rock Slide hits Ho-Oh significantly harder than Thunder, but it doesn't hit any other targets. Close Combat is a physical Fighting-type move that can break through Blissey, and it can also hit most other Steel-types well. Focus Blast inflicts special damage on Steel-types and doesn't lower Xerneas's defenses, but the cost is reduced accuracy and struggling more against Blissey.
Set Details
========
Maximum Special Attack investment is used to ensure high damage output from Moonblast and Xerneas's special coverage moves. A Mild nature is preferred to better switch into Yveltal without forfeiting physical attacking power. Alternatively, a Rash nature is an option for teams that would rather benefit from Xerneas taking physical attacks such as priority moves. 224 Speed EVs are used to outspeed Adamant Rayquaza and all slower threats. The remaining 32 EVs are slotted into Attack, which raises the damage output of Close Combat slightly and increases the probability of Xerneas being able to OHKO standard Ho-Oh with Rock Slide. Xerneas should use a Modest nature if it is not using any physical attacks. A Life Orb gives Xerneas the means of hitting most targets hard either with its Fairy Aura-boosted STAB move or with the appropriate coverage move. An Expert Belt trades a bit of power in exchange for not taking recoil damage; the second benefit, however, is that Xerneas becomes very good at bluffing the much more common Geomancy or Choice Scarf sets.
Usage Tips
========
Although it's not nearly as good at bluffing a Geomancy set as the Choice Scarf set because the Life Orb recoil gives it away after one attack, this initial turn can still be used to make your opponent think you might set up. If using an Expert Belt, this advantage can be extended. Unlike the Geomancy set, this set does not have any bulk investment and is further impacted defensively by Life Orb recoil, so it shouldn't be sent into very many attacks, even if they are resisted. Because this set is strong immediately, it can be used to whittle down many conventional Geomancy Xerneas checks such as Primal Groudon and Klefki because they focus on eliminating a one-time threat. Make use of Aromatherapy support where needed, but be aware that if you aren't using it on the opponent's switch, it may be the last move Xerneas uses before being knocked out. This set doesn't need to worry nearly as much about prediction as the Choice Scarf set because Xerneas won't be locked into its moves and is faster than many of the targets of its coverage move anyway; for this reason, consider making safer plays than when using the Choice Scarf set.
Team Options
========
Primal Groudon can smash Steel-types and Ho-Oh, which may be troublesome for Xerneas to break down, and it benefits from Xerneas checking Yveltal. Calm Mind Arceus formes can be used to break down several Xerneas checks, while a surprise Rock Slide from Xerneas that KOes Ho-Oh can greatly assist Calm Mind Arceus; Calm Mind Arceus formes also benefit from cleric support provided by Aromatherapy. Mega Salamence also benefits from cleric support and can effectively threaten Primal Groudon and Ho-Oh. Calm Mind Primal Kyogre greatly benefits from the pressure that Xerneas can place on opposing Ferrothorn, Blissey, and Primal Groudon. Latias and Latios appreciate cleric support and Xerneas checking Yveltal, and in return they provide anti-hazard support, which can increase the number of times Xerneas can switch in. Giratina-O provides an immunity to Extreme Speed along with the ability to burn Steel-types with Will-O-Wisp, while Xerneas can check Yveltal in return. Users of U-turn and Volt Switch can provide more opportunities for Xerneas to come in, while entry hazard setters can help Xerneas break down Steel-types. Lastly, Healing Wish support can allow Xerneas another chance to wallbreak.

[SET COMMENTS]
Moves
========
Moonblast is by far the best choice for mono-attacking Xerneas, as no Pokemon are immune to the move and many relevant threats get slammed by it. Sleep Talk is used so that the two turns after the use of Rest aren't wasted it and allows Xerneas to directly switch into Dark Void and Spore as sleep fodder with little to lose. Rest is the only recovery move available to Xerneas, although it does fully restore health and eliminate status conditions. Aromatherapy is primarily for cleric support, but it also has a one in three chance to be selected by Sleep Talk, possibly resulting in a shortened Rest. Roar can be used to phaze Pokemon that may attempt to set up and can rack up residual damage from entry hazards.
Set Details
========
248 HP EVs are used to significantly raise defensive Xerneas's mixed bulk. 252 Defense EVs with a Bold nature are used to maximize physical bulk, which helps Xerneas tank blows in a predominantly physical metagame. The remaining 8 EVs are slotted into Special Defense. Leftovers is the preferred held item, as it reduces the number of Pokemon capable of 3HKOing Xerneas while also helping to mitigate residual damage.
Usage Tips
========
Don't underestimate this set's physical bulk. Gyro Ball and Iron Head Aegislash deal pitiful damage, while even Primal Groudon doesn't deal significant damage unless boosted; this translates to having more opportunities to use Aromatherapy and having to use Rest not as frequently. There is a balance to maintain between using Rest too frequently and not enough. If not careful, a high damage roll or critical hit can finish Xerneas right before it has a chance to use Rest. However, using Rest too much means leaving Xerneas more exploitable during the turns it is asleep. Be very wary of Mega Gengar, which can easily trap and eliminate this set. Don't always count on Sleep Talk to produce Moonblast, Aromatherapy, or Roar; a third of the time, the turn will still be wasted if it selects Rest.
Team Options
========
A Pursuit trapper is wanted, as Mega Gengar is very threatening for this set and a means of eliminating it is the best solution. Primal Groudon appreciates the cleric support Xerneas provides and can threaten many common checks to Xerneas such as Steel-types and Ho-Oh. Mega Salamence also appreciates Aromatherapy support and can check Primal Groudon and Ho-Oh for Xerneas. Ghost Arceus and Giratina-O benefit from cleric support and Xerneas's ability to check Yveltal, and in return Ghost Arceus can burn Steel-types with Will-O-Wisp. Latios and Latias greatly appreciate cleric support and Xerneas's ability to check Yveltal, while they can check Primal Groudon and use Defog to remove entry hazards. Ground Arceus can break through the Steel-types that can give defensive Xerneas trouble, and it can also check Primal Groudon. Lugia greatly benefits from cleric support and is a good defensive check for Primal Groudon. If using Roar, Xerneas benefits from having entry hazard setters as partners so that Roar deals residual damage upon phazing.

Moves
========
Calm Mind boosts Xerneas' stats, but the advantages it has over Geomancy are that it can be set up more than once, can be set up consecutively, and doesn't forfeit the item slot. Sleep Talk is used so that turns spent Resting are not always wasted; this allows Xerneas to be able to continually set up Calm Mind or fire off some Moonblasts. Rest is needed in order to maintain longevity and it also removes status ailments such as Toxic, which would otherwise be problematic for this set. Moonblast is the best attacking move for mono-attacking Xerneas, as no Pokemon are immune to it, it is the strongest move available, and has a chance at lowering the opponent's Special Attack stat one stage.
Set Details
========
248 HP EVs are used to increase overall bulk, which aids in the set up of Calm Mind and the use of Rest. 252 Defense EVs with a Bold nature are used to reduce the damage from physical attacks, especially from Aegislash and Primal Groudon. The remaining 8 EVs are placed into Special Defense. Leftovers helps to offset residual damage and makes it more difficult for foes to 3HKO Xerneas before it can use Rest.
Usage Tips
========
This set works best if kept hidden until the end of the match, when strong physical attackers have been eliminated; this makes it much more difficult for the opponent to dispose of this set. Calm Mind quickly allows Xerneas's special bulk to exceed its physical bulk, making it good at taking hits from a variety of attackers. Set up Calm Mind as needed, but be sure not to forget to keep Xerneas healthy enough to use Rest before being knocked out. This set can be used as a status sponge if needed, as Rest can eliminate status at a later time. Maintaining a balance of using Rest is important for this set; too little use means that Xerneas risks being knocked out in a later situation before it is able to heal, while too much use means that Xerneas risks being more vulnerable during turns asleep. Although this set is a passive Calm Mind user that fears phazing, this can be circumvented by using it as a final Pokemon. Note that unlike other Xerneas sets, Calm Mind Xerneas can set up against opposing Klefki.
Team Options
========
One of this set's greatest fears is Mega Gengar, so a Pursuit trapper that can eliminate it is much appreciated. Primal Groudon appreciates the check to Yveltal Xerneas provides and can threaten several checks to Xerneas such as Steel-types and Ho-Oh. Mega Salamence can check Primal Groudon and Ho-Oh for Xerneas. Ghost Arceus and Giratina-O benefit from Xerneas's ability to check Yveltal, and in return Ghost Arceus can burn troublesome Steel-types with Will-O-Wisp. Latios and Latias greatly appreciate Xerneas's ability to check Yveltal, and they can check Primal Groudon, and remove entry hazards with Defog. Hidden Power Fire Latios and Latias especially are great for wearing down Iron Head Aegislash and Ferrothorn. Ground Arceus can break through the Steel-types that can give Calm Mind Xerneas trouble, and it can check Primal Groudon. Lastly, Lugia provides a good defensive check to Primal Groudon that also benefits from Xerneas's ability to check Dark-types.
[STRATEGY COMMENTS]
Other Options
=============
Hidden Power Rock is an option for Geomancy Xerneas that blows through Ho-Oh that have been EVed to survive +2 Thunder, but it doesn't have any other targets. Megahorn on Choice Scarf Xerneas provides slightly higher damage on Mega Mewtwo Y and can be pulled from Sleep Talk to KO Darkrai, but it has little other use. A Pixie Plate on an offensive set is an option that makes Moonblast almost as strong as when boosted by a Life Orb and is very good at bluffing a Geomancy or Choice Scarf set, but opting for Pixie Plate means that coverage options deal less damage. Ingrain protects Xerneas from being phazed and helps alleviate residual damage. Thunder Wave can be used to punish switch-ins that aren't Primal Groudon and greatly impacts a variety of offensive threats, but it doesn't do much to defensive switch-ins. Toxic is usable on a defensive set to hit incoming Primal Groudon, Lugia, and Ho-Oh, although it can be a difficult move to fit. Block can be used in tandem with Rest on a Geomancy set to trap Klefki and allows Xerneas to remove paralysis and set up to +6, although such a set forgoes running coverage moves and isn't always useful in a match. Similarly, a RestTalk Geomancy set can be used along with a bulkier spread in order to break down teams that rely on methods of beating down or revenge killing Xerneas. Misty Terrain can be used to block status moves aimed at Xerneas and is particularly effective against Klefki. Flash Cannon might seem like an appealing move to hit other Fairy-types; however, because neutral Moonblast deals more damage than super effective Flash Cannon, it is nearly always useless.
Checks & Counters
===================
**Primal Groudon**: Although Primal Groudon is not the best defensive Xerneas check, it is certainly the most common and is frequently EVed in response to Geomancy Xerneas. Primal Groudon resists Xerneas's STAB attack, is bulky enough to survive any of its +2 coverage moves at full health, and can retaliate with powerful physical Ground moves, Thunder Wave, or Roar.
**Ho-Oh**: Ho-Oh resists Xerneas's STAB attack and has massive special bulk. Frequently Ho-Oh is EVed to survive +2 Xerneas's Thunder, and it has powerful physical moves such as Sacred Fire and Brave Bird to hit back. Regenerator and Roost make it virtually impossible for Choice Scarf Xerneas to beat down Ho-Oh with Moonblast, while defensive sets take far more from Ho-Oh's attacks than they can deal back.
**Klefki**: With priority Thunder Wave and a resistance to Moonblast, Klefki can switch into Geomancy Xerneas and cripple it with Thunder Wave. The Choice Scarf and Life Orb sets also fear Thunder Wave, although Life Orb Close Combat can beat down Klefki switch-ins. Against defensive sets Klefki can set up Spikes, although Calm Mind Xerneas can set up on Klefki.
**Mega Gengar**: With Shadow Tag, a resistance to Moonblast, and a powerful super effective STAB attack, Mega Gengar is a nightmare for defensive Xerneas sets. It can also check offensive sets if at full health, although Geomancy Xerneas goes right through it if already set up.
**Lugia**: Although Lugia doesn't resist Moonblast, Multiscale in combination with its excellent special bulk means that it can phaze Geomancy Xerneas if at full health and without Stealth Rock in play. It can Toxic stall the Choice Scarf and Life Orb sets in certain scenarios, and the Calm Mind set can be phazed.
**Certain Steel-types**: Aegislash, Excadrill, Genesect, Ferrothorn, Jirachi, Mega Scizor, Mega Metagross, Mega Lucario, and Steel Arceus all pose a general danger for Xerneas sets. Aegislash can defensively check Xerneas sets that aren't Calm Mind, Excadrill can outspeed even offensive Xerneas sets in sand and pound them with Iron Head. Genesect outspeeds all Xerneas sets, excluding a boosted Geomancy Xerneas, and hits hard with Iron Head. Ferrothorn fears Fighting-type coverage moves from offensive threats, but it can hit hard with Gyro Ball and attempt to stall out Xerneas with Leech Seed and/or Toxic. Jirachi is bulky enough to survive any of +2 Xerneas's attacks and can cripple it with Thunder Wave, while Choice Scarf variants can use a fast Iron Head. Mega Scizor, Mega Metagross, and Mega Lucario can all revenge kill Geomancy Xerneas with Bullet Punch and break down defensive sets with strong Steel-type STAB attacks. Lastly, Steel Arceus can nail sets with a powerful super effective Judgment, although it fears Fighting-type coverage.
**Priority**: For offensive teams, priority moves are an effective way of disposing of Geomancy and Choice Scarf Xerneas. This includes Extreme Speed, Bullet Punch, Fake Out, Shadow Sneak, and even Sucker Punch if Xerneas has been weakened enough.
**Blissey**: Blissey has the sheer special bulk to take even +2 Xerneas's attacks, and it can attempt to whittle down Xerneas with Toxic. Blissey stalemates with the support set, but it does fear Close Combat from the Life Orb set.
**Poison Arceus and Fire Arceus**: Both Poison Arceus and Fire Arceus resist Xerneas's STAB attack and have the bulk to take any coverage move, even if Xerneas is at +2. In return, both Poison Arceus and Fire Arceus can retaliate with Thunder Wave or set up Calm Mind.

[OVERVIEW]
The most powerful and versatile Fairy-type available, Xerneas is capable of pulling off a variety of tricks and is able to do them well. The Geomancy set shapes the metagame around it, being one of the most dangerous albeit prepared-for sets in the tier. Although Xerneas's raw stats aren't particularly impressive in a single aspect, its defensive stats are solid and backed up by an above average HP stat, and its base 99 Speed allows Xerneas to outspeed several relevant threats in the Ubers tier. While base 131 Special Attack is good, its not particularly high without a Special Attack boost or a Life Orb, as many other threats in the Ubers tier such as Mewtwo and Kyogre have higher raw offenses and Xerneas's coverage moves aren't boosted by Fairy Aura. Xerneas's ability functions as a buffed Life Orb for Moonblast without forfeiting the item slot or taking recoil, making offensive sets more potent and allowing defensive sets to hit hard without investment. Mono-Fairy typing is good defensively, granting only a few weaknesses along with a handy immunity to the Dragon type. Xerneas is capable of running many coverage moves, although most of these are either weak or have an accuracy drawback. It does have some good support moves such as Aromatherapy and Roar, but the lack of instant recovery means it has to run Rest on a defensive set. Furthermore, Xerneas is afflicted by all entry hazards and by all nonvolatile status, somewhat reducing its defensive synergy. Some Xerneas sets are vulnerable to Shadow Tag Mega Gengar, and Xerneas is impacted by the fact that the most common Pokemon in the tier, Primal Groudon, resists Moonblast.

Moves
========
Geomancy turns Xerneas into a fast, powerful, and specially bulky setup sweeper at the cost of the item slot. Moonblast is the best Fairy-type move available to Xerneas and, when combined with the +2 Special Attack boost from Geomancy, STAB, and Fairy Aura, allows Xerneas to hit very hard. Thunder hits Ho-Oh, Primal Kyogre, Lugia, and most Steel-types. Thunder is always used over Thunderbolt because a super effective Thunderbolt is weaker than a Fairy Aura-boosted STAB Moonblast and thus not worth running. Aromatherapy is an alternate option to Thunder that trades hitting the aforementioned threats for the ability to support teammates in a pinch or remove status from Xerneas. Focus Blast rounds out Xerneas's coverage by hitting Primal Groudon, Ferrothorn, and some other Steel-types. Hidden Power Ground is an alternate, perfectly accurate coverage move that hits Primal Groudon just as hard as Focus Blast and hits Steel-types such as Klefki harder than Moonblast at the cost of not being able to hit Ferrothorn and a few threats such as Steel Arceus as hard as Focus Blast.
Hidden Power Fire can be used to hit Ferrothorn just as hard as Focus Blast without accuracy issues while it also hits Mega Scizor very well and still handles Steel-types in general. Substitute is an option that allows Xerneas to avoid being hit with status. This is particularly useful against Pokemon that rely on Thunder Wave to halt a Xerneas sweep, as Xerneas can set up a Substitute on the turn the foe uses Thunder Wave or as Klefki comes in. It is also an effective move against some defensive Pokemon such as Aegislash and Blissey.
Set Details
========
Maximum Special Attack investment ensures that Xerneas hits as hard as possible once boosted so that it can effectively sweep; the most prominent benchmark is a guaranteed OHKO on maximum HP Arceus formes after Stealth Rock. 44 Speed EVs are used so that Xerneas is faster than Choice Scarf Genesect after a Geomancy boost. 28 Defense EVs give Genesect a Special Attack boost with Download and, when combined with the 184 HP EVs, they allow Xerneas to always survive a +2 standard Extreme Killer Arceus's Extreme Speed after Stealth Rock. A spread of 56 HP / 156 Def / 252 SpA / 44 Spe with a Modest nature can always survive +1 Adamant Mega Salamence's Return and gives Xerneas more physical bulk in general; however, it's 2HKOed by Life Orb Yveltal's Oblivion Wing much more often. A Power Herb allows Xerneas to set up Geomancy in a single turn.
Usage Tips
========
Unlike other setup sweepers such as Dragon Dance Mega Salamence and Extreme Killer Arceus, Geomancy Xerneas can only set up once because a Power Herb is a single-use item. This makes choosing when to set up perhaps the most important aspect of using Geomancy Xerneas. Usually it is not a good idea to set up when the opponent still has healthy Xerneas checks, because this gives up your one opportunity to sweep for little to gain. There are exceptions, however; Xerneas can set up in order to tear down a Pokemon such as Primal Groudon to pave a way for another Pokemon to sweep or can be used to force a trade with a troublesome Pokemon such as Klefki. In general, though, it is best not to set up Geomancy Xerneas until its checks have been eliminated or, more realistically, damaged enough to be blown past. The methods in which an offensive team checks Geomancy Xerneas are usually a different beast entirely. Such teams usually focus on a combination of damaging Xerneas on its setup turn along with the employment of a revenge killer such as Extreme Killer Arceus. Unlike defensive checks, offensive checks cannot be blown past in the same way; it is irrelevant how damaged the opponent's Extreme Killer Arceus or Mega Scizor is because they have priority over Xerneas. This means that unless you benefit from the trade that will occur by setting up Xerneas while a revenge killer is alive, it is best not to set up or, in a rare scenario, attempt to set up in a situation where you won't be damaged on the setup turn so much that you can be revenge killed.
In both cases of knowing when to set up, you must be acquainted with what amount of damage Geomancy Xerneas is capable of taking and dealing. If the opponent has a Rayquaza with Extreme Speed in the back, determine how much you can afford to let Xerneas take when setting up. Similarly, know how much you need to have chipped away at the opposing Lugia before you are ready to sweep. Many teams use Primal Groudon as a check to Geomancy Xerneas, and this can be capitalized upon due to its lack of recovery. Rather than setting up Xerneas right away when a Primal Groudon switch-in is obvious, smack it with Moonblast as it comes in. Switch out, and repeat this the next time you can get Xerneas in for free; after taking two Moonblasts, even specially defensive Primal Groudon can be broken after setting up. Note that Geomancy Xerneas doesn't really want to switch into anything because it is most deadly as a sweeper when at full health. This set can afford to switch into offensive Yveltal; however, Oblivion Wing deals significant damage. Xerneas can be aggressively double switched with in order to break down its checks via offensive partners that perform well against said checks. Because Geomancy Xerneas is good at forcing switches, especially against defensive teams, this provides opportunities to bring in other offensive threats that can start blowing holes in the opposing defensive build. Xerneas has an immunity to Dragon-type moves, and although they are not extremely common, bringing Xerneas in on a predicted Draco Meteor is one of the better methods of getting it into play. In some matchups, a Geomancy Xerneas sweep will be difficult or not worth it; in such scenarios Xerneas can be used more as a team player to aggressively pivot against Pokemon such as Yveltal and Giratina-O.
Team Options
========
Primal Groudon is able to threaten virtually every Xerneas check that isn't Lugia, making it an excellent offensive partner for Geomancy Xerneas. Extreme Killer Arceus is a setup sweeper that pairs well with Geomancy Xerneas for offensive teams due to how they pressure similar checks. Ghost Arceus is a great partner, as Xerneas can threaten Yveltal while Ghost Arceus is immune to Extreme Speed and can break down several Xerneas checks with Will-O-Wisp or Judgment. Mega Salamence provides a method of threatening Primal Groudon and Ho-Oh, which are two of the most common checks to Geomancy Xerneas, and it also performs well against Extreme Killer Arceus; Refresh variants can also provide an excellent switch-in to Sacred Fire from Ho-Oh. Mega Gengar can be used to trap and eliminate several checks to Geomancy Xerneas or force them to trade with Destiny Bond, making it much easier for Xerneas to sweep later on. Ground Arceus plows through almost all defensive Xerneas checks and provides an immunity to Thunder Wave. Darkrai can pressure the defensive backbone of an opposing team, as it is a very difficult Pokemon to switch into, making it easier for Xerneas to break down the foe. Mewtwo formes greatly appreciate Xerneas's ability to check Yveltal and in return can stallbreak against defensive builds that Xerneas may struggle with. Life Orb Zekrom effectively pressures Ho-Oh and can beat down Klefki and Primal Groudon with Bolt Strike and Draco Meteor, respectively. Giratina-O appreciates Xerneas checking Yveltal, can perform well against Primal Groudon, and offers an immunity to Fake Out and Extreme Speed. Lastly, setters of entry hazards make ensuring a Geomancy Xerneas sweep much easier, as Stealth Rock can ensure the KO on Lugia and Ho-Oh while Spikes can break down Primal Groudon and Steel-types.

[SET COMMENTS]
Moves
========
Moonblast is the primary attacking move for this set, as it's not a particularly bad move to be locked into and is the strongest move available for Choice Scarf Xerneas. It also has a good chance at lowering the foe's Special Attack one stage, which can be handy against special attackers that switch into Choice Scarf Xerneas. Focus Blast can hit most targets that resist Moonblast, such as Primal Groudon and Steel-types not named Aegislash. Sleep Talk allows Xerneas to directly switch into Darkrai's Dark Void and potentially knock it out before it can attack again. It also sees use against the rare Spore Smeargle. Aromatherapy allows Xerneas to provide emergency cleric support for its teammates. Thunder allows Xerneas to hit Ho-Oh, Primal Kyogre, and Lugia a bit harder. Grass Knot can hit Primal Groudon just as hard as Focus Blast without the risk of a miss while also hitting Primal Kyogre and a few other threats such as Ground Arceus, Rock Arceus, and Water Arceus. Rock Slide hits Ho-Oh much harder than Thunder, but it doesn't hit anything else.
Set Details
========
252 Special Attack EVs with a Modest nature are used to maximize the damage output of Moonblast, better allowing Xerneas to revenge kill weakened threats and chip away at Pokemon such as Primal Groudon. 224 Speed EVs are used to outspeed +1 Rayquaza and Kyurem-W. 32 EVs are slotted to Defense to ensure that Genesect gets a Special Attack boost from Download. The set revolves around the use of a Choice Scarf, which allows Xerneas to revenge kill threats such as Darkrai, Mewtwo, Shaymin-S, Deoxys-A, and weakened Arceus formes. Running 252 Speed EVs is an option that allows Choice Scarf Xerneas to outspeed maximum Speed Deoxys-A and tie with opposing 252 Speed Choice Scarf Xerneas. If using Rock Slide, the 32 Defense EVs can be invested into Attack, which slightly increases the damage output of Rock Slide but fails to meet a specific benchmark.
Usage Tips
========
Capitalize on the ability to bluff a Geomancy set; this can allow a free KO on a Pokemon that assumed it was faster. One of this set's main draws is that it performs better against Darkrai than most Pokemon, although you mustn't switch it directly into an obvious Sludge Bomb or into Dark Void if you aren't running Sleep Talk. Be very aware of what move Xerneas is being locked into; for example, if your team is in a situation where it cannot afford to allow Mega Salamence to set up, do not KO a Pokemon with a move that is not Moonblast. Aromatherapy is best used on turns where you are certain that the opponent is going to switch because Xerneas is threatening one of their crucial Pokemon. However, if they are going to a Pokemon such as Double Dance Primal Groudon, make sure you can afford to give it one free turn. Prediction is unfortunately a large part of using this set. When considering what Pokemon is going to come in, consider other factors as well, such as risk associated with getting locked into this move against one possible switch-in versus the potential benefit to be gained by predicting correctly.
Team Options
========
Choice Scarf Xerneas is generally a pretty self-reliant set, although a few partners can offer offensive and defensive synergy. Primal Groudon is an effective partner that can deal significant damage to a wide range of typical Choice Scarf Xerneas switch-ins. Furthermore, it benefits from Xerneas's ability to threaten Darkrai and Yveltal. Mega Salamence can provide Choice Scarf Xerneas with a method of threatening Primal Groudon and Ho-Oh, both of which are commonly used to tank Moonblasts. Mega Gengar can eliminate or force a trade with a troublesome Pokemon so that Moonblast spam becomes much more potent. Ghost Arceus and Giratina-O greatly benefit from Xerneas's ability to check Darkrai and Yveltal, and Ghost Arceus performs well against Mega Gengar and can burn troublesome Steel-types with Will-O-Wisp. Latias and Latios also benefit from Xerneas's ability to check Dark-types, and they can offer anti-entry hazard support and threaten Primal Groudon. Ground Arceus is capable of breaking down most checks to Choice Scarf Xerneas, while Rock Arceus can provide a very stable switch-in for Ho-Oh.

Moves
========
Moonblast hits especially hard with both Fairy Aura and a Life Orb, and it is the strongest STAB move available to Xerneas. Aromatherapy allows Xerneas to provide support to teammates, and it can be used on the turn Xerneas forces an opposing Pokemon out. Thunder hits Ho-Oh, Primal Kyogre, and Lugia hard and also hits a few Pokemon that resist Moonblast and resist or are immune to Fighting-ype coverage moves, such as Aegislash and Poison Arceus. Rock Slide hits Ho-Oh significantly harder than Thunder, but it doesn't hit any other targets. Close Combat is a physical Fighting-type move that can break through Blissey, and it can also hit most other Steel-types well. Focus Blast inflicts special damage on Steel-types and doesn't lower Xerneas's defenses, but the cost is reduced accuracy and struggling more against Blissey.
Set Details
========
Maximum Special Attack investment is used to ensure high damage output from Moonblast and Xerneas's special coverage moves. A Mild nature is preferred to better switch into Yveltal without forfeiting physical attacking power. Alternatively, a Rash nature is an option for teams that would rather benefit from Xerneas taking physical attacks such as priority moves. 224 Speed EVs are used to outspeed Adamant Rayquaza and all slower threats. The remaining 32 EVs are slotted into Attack, which raises the damage output of Close Combat slightly and increases the probability of Xerneas being able to OHKO standard Ho-Oh with Rock Slide. Xerneas should use a Modest nature if it is not using any physical attacks. A Life Orb gives Xerneas the means of hitting most targets hard either with its Fairy Aura-boosted STAB move or with the appropriate coverage move. An Expert Belt trades a bit of power in exchange for not taking recoil damage; the second benefit, however, is that Xerneas becomes very good at bluffing the much more common Geomancy or Choice Scarf sets.
Usage Tips
========
Although it's not nearly as good at bluffing a Geomancy set as the Choice Scarf set because the Life Orb recoil gives it away after one attack, this initial turn can still be used to make your opponent think you might set up. If using an Expert Belt, this advantage can be extended. Unlike the Geomancy set, this set does not have any bulk investment and is further impacted defensively by Life Orb recoil, so it shouldn't be sent into very many attacks, even if they are resisted. Because this set is strong immediately, it can be used to whittle down many conventional Geomancy Xerneas checks such as Primal Groudon and Klefki because they focus on eliminating a one-time threat. Make use of Aromatherapy support where needed, but be aware that if you aren't using it on the opponent's switch, it may be the last move Xerneas uses before being knocked out. This set doesn't need to worry nearly as much about prediction as the Choice Scarf set because Xerneas won't be locked into its moves and is faster than many of the targets of its coverage move anyway; for this reason, consider making safer plays than when using the Choice Scarf set.
Team Options
========
Primal Groudon can smash Steel-types and Ho-Oh, which may be troublesome for Xerneas to break down, and it benefits from Xerneas checking Yveltal. Calm Mind Arceus formes can be used to break down several Xerneas checks, while a surprise Rock Slide from Xerneas that KOes Ho-Oh can greatly assist Calm Mind Arceus; Calm Mind Arceus formes also benefit from cleric support provided by Aromatherapy. Mega Salamence also benefits from cleric support and can effectively threaten Primal Groudon and Ho-Oh. Calm Mind Primal Kyogre greatly benefits from the pressure that Xerneas can place on opposing Ferrothorn, Blissey, and Primal Groudon. Latias and Latios appreciate cleric support and Xerneas checking Yveltal, and in return they provide anti-hazard support, which can increase the number of times Xerneas can switch in. Giratina-O provides an immunity to Extreme Speed along with the ability to burn Steel-types with Will-O-Wisp, while Xerneas can check Yveltal in return. Users of U-turn and Volt Switch can provide more opportunities for Xerneas to come in, while entry hazard setters can help Xerneas break down Steel-types. Lastly, Healing Wish support can allow Xerneas another chance to wallbreak.

[SET COMMENTS]
Moves
========
Moonblast is by far the best choice for mono-attacking Xerneas, as no Pokemon are immune to the move and many relevant threats get slammed by it. Sleep Talk is used so that the two turns after the use of Rest aren't wasted it and allows Xerneas to directly switch into Dark Void and Spore as sleep fodder with little to lose. Rest is the only recovery move available to Xerneas, although it does fully restore health and eliminate status conditions. Aromatherapy is primarily for cleric support, but it also has a one in three chance to be selected by Sleep Talk, possibly resulting in a shortened Rest. Roar can be used to phaze Pokemon that may attempt to set up and can rack up residual damage from entry hazards.
Set Details
========
248 HP EVs are used to significantly raise defensive Xerneas's mixed bulk. 252 Defense EVs with a Bold nature are used to maximize physical bulk, which helps Xerneas tank blows in a predominantly physical metagame. The remaining 8 EVs are slotted into Special Defense. Leftovers is the preferred held item, as it reduces the number of Pokemon capable of 3HKOing Xerneas while also helping to mitigate residual damage.
Usage Tips
========
Don't underestimate this set's physical bulk. Gyro Ball and Iron Head Aegislash deal pitiful damage, while even Primal Groudon doesn't deal significant damage unless boosted; this translates to having more opportunities to use Aromatherapy and having to use Rest not as frequently. There is a balance to maintain between using Rest too frequently and not enough. If not careful, a high damage roll or critical hit can finish Xerneas right before it has a chance to use Rest. However, using Rest too much means leaving Xerneas more exploitable during the turns it is asleep. Be very wary of Mega Gengar, which can easily trap and eliminate this set. Don't always count on Sleep Talk to produce Moonblast, Aromatherapy, or Roar; a third of the time, the turn will still be wasted if it selects Rest.
Team Options
========
A Pursuit trapper is wanted, as Mega Gengar is very threatening for this set and a means of eliminating it is the best solution. Primal Groudon appreciates the cleric support Xerneas provides and can threaten many common checks to Xerneas such as Steel-types and Ho-Oh. Mega Salamence also appreciates Aromatherapy support and can check Primal Groudon and Ho-Oh for Xerneas. Ghost Arceus and Giratina-O benefit from cleric support and Xerneas's ability to check Yveltal, and in return Ghost Arceus can burn Steel-types with Will-O-Wisp. Latios and Latias greatly appreciate cleric support and Xerneas's ability to check Yveltal, while they can check Primal Groudon and use Defog to remove entry hazards. Ground Arceus can break through the Steel-types that can give defensive Xerneas trouble, and it can also check Primal Groudon. Lugia greatly benefits from cleric support and is a good defensive check for Primal Groudon. If using Roar, Xerneas benefits from having entry hazard setters as partners so that Roar deals residual damage upon phazing.

Moves
========
Calm Mind boosts Xerneas' stats, but the advantages it has over Geomancy are that it can be set up more than once, can be set up consecutively, and doesn't forfeit the item slot. Sleep Talk is used so that turns spent Resting are not always wasted; this allows Xerneas to be able to continually set up Calm Mind or fire off some Moonblasts. Rest is needed in order to maintain longevity and it also removes status ailments such as Toxic, which would otherwise be problematic for this set. Moonblast is the best attacking move for mono-attacking Xerneas, as no Pokemon are immune to it, it is the strongest move available, and has a chance at lowering the opponent's Special Attack stat one stage.
Set Details
========
248 HP EVs are used to increase overall bulk, which aids in the set up of Calm Mind and the use of Rest. 252 Defense EVs with a Bold nature are used to reduce the damage from physical attacks, especially from Aegislash and Primal Groudon. The remaining 8 EVs are placed into Special Defense. Leftovers helps to offset residual damage and makes it more difficult for foes to 3HKO Xerneas before it can use Rest.
Usage Tips
========
This set works best if kept hidden until the end of the match, when strong physical attackers have been eliminated; this makes it much more difficult for the opponent to dispose of this set. Calm Mind quickly allows Xerneas's special bulk to exceed its physical bulk, making it good at taking hits from a variety of attackers. Set up Calm Mind as needed, but be sure not to forget to keep Xerneas healthy enough to use Rest before being knocked out. This set can be used as a status sponge if needed, as Rest can eliminate status at a later time. Maintaining a balance of using Rest is important for this set; too little use means that Xerneas risks being knocked out in a later situation before it is able to heal, while too much use means that Xerneas risks being more vulnerable during turns asleep. Although this set is a passive Calm Mind user that fears phazing, this can be circumvented by using it as a final Pokemon. Note that unlike other Xerneas sets, Calm Mind Xerneas can set up against opposing Klefki.
Team Options
========
One of this set's greatest fears is Mega Gengar, so a Pursuit trapper that can eliminate it is much appreciated. Primal Groudon appreciates the check to Yveltal Xerneas provides and can threaten several checks to Xerneas such as Steel-types and Ho-Oh. Mega Salamence can check Primal Groudon and Ho-Oh for Xerneas. Ghost Arceus and Giratina-O benefit from Xerneas's ability to check Yveltal, and in return Ghost Arceus can burn troublesome Steel-types with Will-O-Wisp. Latios and Latias greatly appreciate Xerneas's ability to check Yveltal, and they can check Primal Groudon, and remove entry hazards with Defog. Hidden Power Fire Latios and Latias especially are great for wearing down Iron Head Aegislash and Ferrothorn. Ground Arceus can break through the Steel-types that can give Calm Mind Xerneas trouble, and it can check Primal Groudon. Lastly, Lugia provides a good defensive check to Primal Groudon that also benefits from Xerneas's ability to check Dark-types.
[STRATEGY COMMENTS]
Other Options
=============
Hidden Power Rock is an option for Geomancy Xerneas that blows through Ho-Oh that have been EVed to survive +2 Thunder, but it doesn't have any other targets. Megahorn on Choice Scarf Xerneas provides slightly higher damage on Mega Mewtwo Y and can be pulled from Sleep Talk to KO Darkrai, but it has little other use. A Pixie Plate on an offensive set is an option that makes Moonblast almost as strong as when boosted by a Life Orb and is very good at bluffing a Geomancy or Choice Scarf set, but opting for Pixie Plate means that coverage options deal less damage. Ingrain protects Xerneas from being phazed and helps alleviate residual damage. Thunder Wave can be used to punish switch-ins that aren't Primal Groudon and greatly impacts a variety of offensive threats, but it doesn't do much to defensive switch-ins. Toxic is usable on a defensive set to hit incoming Primal Groudon, Lugia, and Ho-Oh, although it can be a difficult move to fit. Block can be used in tandem with Rest on a Geomancy set to trap Klefki and allows Xerneas to remove paralysis and set up to +6, although such a set forgoes running coverage moves and isn't always useful in a match. Similarly, a RestTalk Geomancy set can be used along with a bulkier spread in order to break down teams that rely on methods of beating down or revenge killing Xerneas. Misty Terrain can be used to block status moves aimed at Xerneas and is particularly effective against Klefki. Flash Cannon might seem like an appealing move to hit other Fairy-types; however, because neutral Moonblast deals more damage than super effective Flash Cannon, it is nearly always useless.
Checks & Counters
===================
**Primal Groudon**: Although Primal Groudon is not the best defensive Xerneas check, it is certainly the most common and is frequently EVed in response to Geomancy Xerneas. Primal Groudon resists Xerneas's STAB attack, is bulky enough to survive any of its +2 coverage moves at full health, and can retaliate with powerful physical Ground moves, Thunder Wave, or Roar.
**Ho-Oh**: Ho-Oh resists Xerneas's STAB attack and has massive special bulk. Frequently Ho-Oh is EVed to survive +2 Xerneas's Thunder, and it has powerful physical moves such as Sacred Fire and Brave Bird to hit back. Regenerator and Roost make it virtually impossible for Choice Scarf Xerneas to beat down Ho-Oh with Moonblast, while defensive sets take far more from Ho-Oh's attacks than they can deal back.
**Klefki**: With priority Thunder Wave and a resistance to Moonblast, Klefki can switch into Geomancy Xerneas and cripple it with Thunder Wave. The Choice Scarf and Life Orb sets also fear Thunder Wave, although Life Orb Close Combat can beat down Klefki switch-ins. Against defensive sets Klefki can set up Spikes, although Calm Mind Xerneas can set up on Klefki.
**Mega Gengar**: With Shadow Tag, a resistance to Moonblast, and a powerful super effective STAB attack, Mega Gengar is a nightmare for defensive Xerneas sets. It can also check offensive sets if at full health, although Geomancy Xerneas goes right through it if already set up.
**Lugia**: Although Lugia doesn't resist Moonblast, Multiscale in combination with its excellent special bulk means that it can phaze Geomancy Xerneas if at full health and without Stealth Rock in play. It can Toxic stall the Choice Scarf and Life Orb sets in certain scenarios, and the Calm Mind set can be phazed.
**Certain Steel-types**: Aegislash, Excadrill, Genesect, Ferrothorn, Jirachi, Mega Scizor, Mega Metagross, Mega Lucario, and Steel Arceus all pose a general danger for Xerneas sets. Aegislash can defensively check Xerneas sets that aren't Calm Mind, Excadrill can outspeed even offensive Xerneas sets in sand and pound them with Iron Head. Genesect outspeeds all Xerneas sets, excluding a boosted Geomancy Xerneas, and hits hard with Iron Head. Ferrothorn fears Fighting-type coverage moves from offensive threats, but it can hit hard with Gyro Ball and attempt to stall out Xerneas with Leech Seed and/or Toxic. Jirachi is bulky enough to survive any of +2 Xerneas's attacks and can cripple it with Thunder Wave, while Choice Scarf variants can use a fast Iron Head. Mega Scizor, Mega Metagross, and Mega Lucario can all revenge kill Geomancy Xerneas with Bullet Punch and break down defensive sets with strong Steel-type STAB attacks. Lastly, Steel Arceus can nail sets with a powerful super effective Judgment, although it fears Fighting-type coverage.
**Priority**: For offensive teams, priority moves are an effective way of disposing of Geomancy and Choice Scarf Xerneas. This includes Extreme Speed, Bullet Punch, Fake Out, Shadow Sneak, and even Sucker Punch if Xerneas has been weakened enough.
**Blissey**: Blissey has the sheer special bulk to take even +2 Xerneas's attacks, and it can attempt to whittle down Xerneas with Toxic. Blissey stalemates with the support set, but it does fear Close Combat from the Life Orb set.
**Poison Arceus and Fire Arceus**: Both Poison Arceus and Fire Arceus resist Xerneas's STAB attack and have the bulk to take any coverage move, even if Xerneas is at +2. In return, both Poison Arceus and Fire Arceus can retaliate with Thunder Wave or set up Calm Mind.
