Arceus
[Overview]
<p>The oldest Pokemon returns, in its fossil form, to the treacherous environment known the 5th generation Uber metagame, by holding a Stone Plate. While it has not been given anything new other than the ability to use full EVs, Rock Arceus can now effectively counter quite a few new Pokemon. With excellent all-round stats, it is one of the few Pokemon that can boast being able to counter both Ho-Oh and Reshiram. In sandstorm, its Special Defense is so massive that even unfathomably powerful attacks such as Draco Meteor from Choice Specs Dialga simply bounce straight off. Rock Arceus is possibly one of the most versatile and unpredictable Arceus formes, being able to utilize Calm Mind and Swords Dance with equal efficiency while also being able to serve as a fantastic support Pokemon.</p>
<p>This is not to say that Rock Arceus is without its downsides. While its defenses are phenomenal, especially in a sandstorm, its Rock typing gives it weaknesses to five very common attacking types. A susceptibility to all three forms of entry hazards and somewhat of an over-reliance on weather in a tier littered with Toxic Spikes and weather changers do not help its cause, either. Use Rock Arceus to its advantages and it will be a great asset, but you must be aware of its weaknesses.</p>
[SET]

[SET COMMENTS]
<p>Rock Arceus's huge bulk and great STAB allow it to run an effective mono-attacker set. This set is useful for a number of reasons. Firstly, with sandstorm support and its pure Rock typing, Arceus is a fantastic counter to many dangerous Pokemon. With its Rock-type Judgement, it can quickly put Ho-Oh and Reshiram in their place; with Will-O-Wisp, it can easily cripple Normal Arceus. It is an excellent to check to the Extreme Killer while maintaining a STAB with decent coverage. Under sandstorm, it can also switch into some of the most powerful special attacks in the Uber tier. For example, Draco Meteor from Modest Choice Specs Dialga only does 53.60% - 63.51%, allowing Rock Arceus to heal off the damage and stall Dialga out. Secondly, with access to Calm Mind, Rock Arceus can switch from a defensive Pokemon into a deadly sweeper in the blink of an eye, and any team that lacks an appropriate counter for it will quickly be crushed. This allows Arceus to easily control the tempo of the match, switching between offense and defense at will. While this set is at its best on sandstorm teams, its utility does not end there. It can offer sun teams an excellent check to Fire-types, who are even more dangerous in the sun.</p>
<p>Calm Mind is obviously the crux of the set, boosting Arceus's excellent Special Attack to levels where it can sweep while sending its already bloated Special Defense to untouchable levels. Judgement is obviously Arceus's STAB, while Recover allows it to switch in again and again. The last slot comes down to the user's preference. Will-O-Wisp complements Calm Mind and Judgement almost perfectly, allowing Arceus to cripple physical attackers such as Groudon and Garchomp who might try to bypass its Special Defense with physical attacks. Refresh, on the other hand, allows Arceus to laugh at status, especially from the likes of Blissey and Chansey.</p>
[ADDITIONAL COMMENTS]
<p>Roar is usable over Will-O-Wisp or Refresh to allow Arceus to defeat opposing Calm Mind users that might attempt to engage in a Calm Mind war. Substitute is usable to get past Chansey and Blissey, but Refresh is better overall due to its ability to cure poison inflicted by Toxic Spikes. Otherwise, stick to the moves given for maximum efficacy. The EVs and nature aim to maximize bulk while allowing Arceus to Speed-tie with opposing Arceuses.</p>
<p>Rock Arceus is obviously best used in sandstorm, which means Tyranitar or Hippowdon should be used alongside it. Unfortunately, this will add additional Water-, Grass-, Ground-, Steel- and Fighting-type weaknesses, so teammates that resist these types are helpful. Shaymin-S is an excellent Pokemon to run alongside Arceus, as it resists most of Arceus's weaknesses, while Arceus can easily take Fire-type moves and weaker special attacks such as Ice Beam for Shaymin-S. Giratina and Lugia also synergise very well with Rock Arceus, switching into most of Arceus' weaknesses with ease. Giratina is especially good because it can switch into Choice Scarf Terrakion and Choice Scarf Heracross, who can both deal huge amounts of damage to Rock Arceus, the latter enjoying a switch into Will-O-Wisp as well.</p>
<p>While this set can be extremely threatening, it is hard-countered by Ground, Steel, Fighting, Grass and Water Arceus, who can all set up Calm Mind alongside Rock Arceus and bring it down with their own super effective Judgements. Ho-Oh is an excellent teammate who can bring down all of the aforementioned Arceus formes barring Water Arceus due to its huge Special Defense and powerful STAB attacks. Fighting Arceus can also be defeated easily by Psystrike Mewtwo, provided that it avoids switching into Shadow Ball or Dark Pulse. Dialga can deal with Water Arceus without much trouble. If Rock Arceus lacks Refresh, Chansey and Blissey can easily take anything it throws at them and cripple it with Toxic; if it lacks Will-O-Wisp, Groudon and Garchomp can freely switch in and take it out with super effective Earthquakes. Since sandstorm will likely be used alongside Arceus, Excadrill can easily switch into Chansey and Blissey, as it is immune to both Thunder Wave and Toxic, and proceed to set up Swords Dance to sweep. Scizor and Lucario can work in a similar fashion. Finally, Kyogre is also a huge problem to Rock Arceus, being able to use Calm Mind alongside it and drown it with its Water-STAB, or outspeed and OHKO with Water Spout if Kyogre is holding a Choice Scarf. Grass-types such as Celebi, Virizion and Shaymin-S synergise well with Arceus. Palkia also boasts being able to switch into Kyogre's Water-type attacks with its 4x resistance to Water-type attacks.</p>

[SET COMMENTS]
<p>While the previous set focused on using Rock Arceus's defensive capabilities to pull off a sweep, this set takes full advantage of its excellent Special Attack, Speed, bulk, and coverage to pull off a sweep as quickly as possible. After a single Calm Mind, Arceus reaches 508 or 558 Special Attack depending on its nature, dealing huge amounts of damage to weakened teams. Judgement is its STAB attack, which hits most Pokemon that do not resist it extremely hard. Fire Blast allows Arceus to roast Steel Arceus that may attempt to Calm Mind alongside it, as well as other Steel-types such as Ferrothorn and Jirachi. Grass Knot, on the other hand, allows Rock Arceus to destroy any Groudon and Kyogre that think they can change the weather and stop Arceus with their super effective STAB attacks. Recover is preferred in the last slot, as it allows Arceus to still check dangerous threats such as Reshiram and Ho-Oh, but an additional coverage move can be used for maximum coverage.</p>
[ADDITIONAL COMMENTS]
<p>Earth Power can be used in place of Fire Blast or Grass Knot if you want to hit Dialga harder, although if Rock Arceus is using Recover, specially based Dialga that lack Toxic, Roar, or Dragon Tail can be used as set-up bait anyway. Ice Beam can also be used to defeat Garchomp, who can otherwise cause Arceus a lot of trouble, but Ice Beam is quite useless otherwise. Psyshock is in a similar vein, as it allows Rock Arceus to severely damage but not much else. The EVs are simple: they just max out Special Attack and Speed, allowing Arceus to be as fast and powerful as possible. A Timid nature allows Rock Arceus to Speed-tie with other Arceus formes, and also lets it outspeed Lugia, Latias, Latios, Terrakion, Tornadus, and Thundurus. A Modest nature allows Arceus to hit harder while still outspeeding Garchomp that don't use a Choice Scarf.</p>
<p>Like all Rock Arceus variants, this set is hard-countered by Fighting Arceus. Again, Ho-Oh and Mewtwo are excellent teammates for this reason. Chansey and Blissey now completely wall this set, so again, Excadrill is a good teammate, as are Scizor, Terrakion, Garchomp, and Lucario. Wobbuffet can be used to trap Chansey or Blissey through the use of Encore and Tickle, allowing Tyranitar to come in and Pursuit them to and ensure they cannot take Rock Arceus's attacks any more. Garchomp resists both Judgement and Fire Blast, does not take much damage from Grass Knot, and can defeat Arceus with STAB Earthquake. Physically inclined Dialga, especially those with Bulk Up, can set up alongside Rock Arceus and destroy it with Outrage or Earthquake. Speaking of Dialga, a Bulk Up RestTalk Dialga of your own can come in very handy. It can switch into Chansey and Blissey with impunity, as well as check Water Arceus and Calm Mind Kyogre. It can also lure in Garchomp, survive Earthquake and OHKO in return with Outrage. Forretress and Ferrothorn are also decent checks to opposing Garchomp and can set up Stealth Rock and Spikes, which would whittle down Garchomp health so it cannot take Rock Arceus's attacks any more.</p>
[SET]
name: Swords Dance

move 3: Earthquake
move 4: Recover
item: Stone Plate
nature: Jolly
evs: 4 HP / 252 Atk / 252 Spe
[SET COMMENTS]
<p>Rock Arceus is one of the select few Arceus formes that can run a viable Swords Dance set, and also the only Swords Dancing Arceus that can defeat Skarmory without depending on weather. While Swords Dance Arceus may seem more appealing than the Calm Mind variant due to its ability to boost its Attack more quickly, it does have a few disadvantages. Firstly, it can no longer switch into Ho-Oh as easily, as Sacred Fire has a 47.5% chance of crippling it, factoring in accuracy. Secondly, it is very easily walled, especially by Groudon, who poses a huge threat to sandstorm teams in general. That being said, Swords Dance Rock Arceus is still an extremely potent sweeper. To illustrate its power, after a single Swords Dance, Jolly Arceus can OHKO specially defensive Skarmory after Stealth Rock damage most of the time. Stone Edge is Rock Arceus' powerful albeit inaccurate STAB attack. STAB on Stone Edge is what differentiates Rock Arceus from Ground Arceus, who runs the same set. Earthquake gives Arceus fantastic coverage alongside Stone Edge. Recover allows Arceus to recover lost health and check threats such as Reshiram more easily.</p>
[ADDITIONAL COMMENTS]
<p>Arceus has a few other options that it can run in the last slot. Overheat allows Rock Arceus to deal huge amounts of damage to Ferrothorn if it's not raining, who would otherwise prove to be a huge nuisance. ExtremeSpeed can allow it to take out frailer, faster Pokemon such as Shaymin-S and Darkrai, while Brick Break can be used to beat down Ferrothorn in the rain. A Jolly nature is preferred as it allows Rock Arceus to Speed-tie with opposing Arceuses as well as outspeed Terrakion and Lugia, two Pokemon that would be problematic. However, an Adamant nature guarantees Arceus the OHKO on Skarmory after Stealth Rock damage.</p>
<p>Fighting Arceus remains a hard counter to this set as well. Again, Ho-Oh and Mewtwo are fantastic checks to Fighting Arceus. They also laugh at Virizion, who resists Stone Edge and Earthquake. Groudon and Ground Arceus now wall Rock Arceus and take it out with a super effective Earthquake or Judgement. Garchomp, should it be at high health, will also cause problems for Rock Arceus. Again, Grass-types such as Shaymin-S, Virizion and Celebi do very well against them, and if you are using Rock Arceus as a standalone Pokemon, a Groudon of your own also defeats them quite handily. Ferrothorn is also a problem if you lack Overheat. Magnezone can be used to trap and KO the steel plant.</p>
[Other Options]
<p>While Arceus has an abundant Special movepool to work from, none of its other options add more coverage than what is recommended. Flamethrower can be used if you find Fire Blast's accuracy off-putting. Focus Blast can be used to hit Steel-types and Dialga super effectively in place of Fire Blast, but its inaccuracy makes it a poor option. Thunder can be used to hit Kyogre extremely hard while having a high paralysis chance, but since Grass Knot does the same amount of damage, Thunder is generally not preferred.</p>
<p>Rock Arceus can also run a mono-attacking Swords Dance set with Swords Dance / Recover / Refresh / Rock Slide, but Calm Mind is generally better. It is much easier to wall such a set regardless. Arceus can also run a rather useful dual screens set, as well as a very bulky Cosmic Power stall set. It can also drop Calm Mind on the Mono-Attacker set to run a full support set with Roar, Perish Song, or Stealth Rock in its place, should you desire it.</p>
[Checks and Counters]
<p>As alluded to in the individual set descriptions, Fighting Arceus is Rock Arceus's number one enemy. It resists Rock Arceus' STAB and is neutral to Rock Arceus' commonly used coverage moves, allowing it to set up Calm Mind alongside Rock Arceus and take it down with its super effective Fighting-type Judgement. Steel and Ground Arceus can work in a similar fashion, but need to watch out for Fire Blast and Grass Knot, respectively. Grass and Water Arceus both have a super effective Judgement to use on Rock Arceus as well, but both need to watch out for Fire Blast and Grass Knot, respectively, while boosted neutral Rock-type Judgements will also hurt.</p>
<p>Any special variant of Rock Arceus that lacks Substitute or Refresh is walled by Chansey and Blissey, who can both shrug off any attack Arceus can throw at them and cripple Arceus with Toxic. If Arceus lacks Grass Knot or Will-O-Wisp, Groudon can switch in without fear and KO it with Earthquake. Garchomp works in a similar vein, only fearing the rare Ice Beam, whereas Excadrill can switch into anything not named Earthquake, Will-O-Wisp or Fire Blast and KO with Earthquake. Kyogre causes problems for special variants of Rock Arceus that lack Grass Knot, as its enormous Special Defense allows it to tank anything Rock Arceus throws at it, while Arceus is forced to switch to avoid taking STAB Water-type attacks to the face. Choice Scarf Kyogre can outspeed and OHKO Rock Arceus with Water Spout, even after a Calm Mind. Choice Scarf Terrakion and Heracross can revenge kill weakened Rock Arceus, the latter also enjoys being burned by Will-O-Wisp. Groudon and Ground Arceus will a field day against Swords Dance Rock Arceus, while Giratina and Ferrothorn can use Will-O-Wisp or Leech Seed to stall out Rock Arceus. Be aware that should Arceus carry Overheat, Ferrothorn should stay well away unless it has rain support.</p>
