Overview
########
Arceus-Normal returns to Ubers as threatening in ORAS as it was in XY. With the strongest priority in the Ubers tier, fantastic 120 base stats across the board, (comma) and a wide array of coverage moves that, Arceus-Normal makes for a fantastic late-game sweeper that can easily set up and sweep mid- to or late-game once its checks and counters are even slightly weakened. However, a huge part of Arceus-Normal's viability also comes from its ability to serve as a very strong revenge killer for its team, taking out weakened offensive threats with its Life Orb Extreme Speed. Arceus-Normal also pairs off well with new arrival Primal Groudon both offensively and defensively, with the two breaking physical walls for each other or Primal Groudon simply providing Stealth Rock support, Lava Pluming physical walls, and absorbing Will-O-Wisp absorber. Arceus-Normal also fares well against opposing Primal Groudon due to its new weakness to Ground, allowing Arceus-Normal to break through with Earthquake. Arceus-Normal also appreciates the decline of Will-O-Wisp Support Arceus, regular non-Primal Groudon, (comma) and Landorus-Therian in the generation transition, competent checks in XY. However, a new check in Mega Salamence has been introduced, and old checks such as Mega Gengar are still viable. The indirect rise of Arceus-Ghost due to Latias and Latios is not particularly appreciated either.
Extremekiller
########
name: Extremekiller
move 1: Swords Dance
move 2: Extreme Speed
move 3: Shadow Claw / Stone Edge
move 4: Earthquake
ability: Multitype
item: Life Orb
evs: 4 HP / 252 Atk / 252 Spe
nature: Jolly
Moves
========
Swords Dance allows (changed this because you use 'allowing' later in the sentence) doubles Arceus-Normal's to double its Attack, allowing it to OHKO various Pokemon such as Mewtwo and offensive Yveltal with little or no prior damage. Extreme Speed allows Arceus-Normal to bypass Speed tiers and Choice Scarf users, and it can and should be used to revenge kill Pokemon things such as Darkrai, Mega Mewtwo Y, (comma) and Blaziken after they are even slightly weakened. Earthquake should be used to break through Primal Groudon, as well as Steel- and Rock-types, namely Dialga, Arceus-Rock, (comma) and Mega Diancie, while and Shadow Claw is used to break through Lugia and Ghost-types, namely Arceus-Ghost and Giratina-Origin, and Lugia. Stone Edge can be used to break through Lugia, defensive Yveltal, Mega Salamence, (comma) and Ho-Oh with in one moveslot.
Various other coverage moves can be used in lieu of Shadow Claw or Earthquake, although Earthquake tends to be needed the most. Ice Beam takes out Mega Salamence after Stealth Rock, OHKOes the albeit rare Landorus-Therian and Gliscor after Stealth Rock as well, and can also 2HKO regular Groudon. Overheat or Fire Blast can be used to blow Ferrothorn and Mega Scizor away, with Fire Blast also 2HKOing regular Groudon thanks to Drought. Lastly, Shadow Force can be used to OHKO Arceus-Ghost and Giratina-Origin, and also blocks Defog, but bear in mind it is easy for the opponent to switch in a Pokemon that resists or is immune to into a Ghost resist or immunity due to during the charge turn, and Lugia is also given a free turn to Roost back to full health and reactivate Multiscale.
Set Details
========
Maximum Attack and Speed investment allows Arceus-Normal to at worst Speed tie with opposing Arceus. Life Orb grants a significant power boost to all of Arceus-Normal's its attacks. Either Silk Scarf or Lum Berry can be used alongside an Adamant nature and a more bulky spread of 240 HP / 252 Atk / 16 Spe, or 200 HP / 252 Atk / 56 Spe (maybe mention the advantages of this spread?), both of which can also use a Lum Berry.
Usage Tips
========
Don't just use Arceus-Normal late-game, as it's an amazing revenge killer that can take out dangerous opposing threats when they are weakened. Do not set Setting up while checks are still healthy is stupid, as you should be using teammates to wear them down to the point where Arceus can OHKO them and avoid taking damage or status. You should also wear down Will-O-Wisp users as well.
Similarly, do not set Setting up on powerful attacks such as something like Primal Kyogre's Origin Pulse, (comma) is stupid as it means that Arceus-Normal takes a huge amount of damage from them and can no longer sweep due to it being in KO range of opposing priority attacks, as well as being able to take fewer turns of recoil from Life Orb. Setting up on moves such as Latios and Latias's things like Lati@s's -2 Draco Meteor is smarter, or good as it means Arceus-Normal doesn't get blasted on the turn it sets up.
When revenge killing bulky opposing threats that are bulky, it is necessary to deal significant damage to them as they set up so that Arceus can revenge kill them easily. Pokemon Things such as Primal Groudon, Xerneas, (comma) and Mega Salamence need to be significantly weakened in order for Extreme Speed to KO them after you sacrifice a Pokemon something to bring Arceus in safely. For Pokemon such as things like Darkrai, Mega Mewtwo Y, (comma) and Blaziken, only a slight amount of prior damage is needed to put puts them into Extreme Speed range, but it is wise to calculate whether they will fall to Extreme Speed or not before trying to revenge kill them.
Team Options
========
Primal Groudon absorbs burns for Arceus-Normal while setting up Stealth Rock and potentially weakening Lugia with either Lava Plume burns, Toxic, (comma) or Stone Edge. Darkrai or Yveltal can be double switched into Arceus-Ghost, Giratina-Origin, (comma) and Lugia, either KOing them or forcing them out and making them take more entry hazard damage the next time they come in. Shadow Ball Mega Gengar can trap checks such as Lugia and severely weakens Arceus-Ghost as well, and it can also run Hidden Power Fire for Ferrothorn or Mega Scizor. Xerneas can easily switch into defensive Yveltal, with Choice Scarf and Geomancy Xerneas both working very well on the kinds of teams Extremekiller Arceus finds itself on. Healing Wish Latias can be used to bring Extremekiller Arceus back for a second go at the opponent's team as well.
How Refreshing
########
name: How Refreshing Extremekiller (name has to be the same as the above)
move 1: Refresh
move 2: Swords Dance
move 3: Extreme Speed
move 4: Shadow Claw
ability: Multitype
item: Silk Scarf
evs: 4 HP / 252 Atk / 252 Spe
nature: Jolly
Moves
========
Refresh allows Arceus-Normal to absorb Will-O-Wisp and heal it easily. Swords Dance doubles Arceus's lets Arceus double its Attack, with Extreme Speed being the obvious STAB move of choice. Shadow Claw lets Arceus-Normal break through Arceus-Ghost, Giratina-Origin, (comma) and Lugia.
Set Details
========
Again, max (no cross-set referencing) Maximum Attack and Speed investment should be used so that Arceus-Normal can at worst Speed tie with opposing Arceus. Silk Scarf boosts the power of Extreme Speed without causing recoil damage.
Usage Tips
========
Again, don't Don't just use Arceus-Normal late-game,; (semicolon) it's an amazing revenge killer that can take out weakened threats. Refresh Arceus should also be used as an Arceus-Ghost check, (comma) as the ability to absorb Will-O-Wisp and + an immunity to Ghost-type Judgment means Arceus-Normal can set up Swords Dances on it, and, with some luck, can break through it Arceus-Ghost without being burned at the end of the exchange. Don't be afraid to let Arceus-Normal take a Will-O-Wisp or a Toxic if it lets it Arceus-Normal KO something important, as the status can always be Refreshed away later.
As always, setting Setting up on a powerful attack, such as Mega Salamence's Return or Double-Edge, is a bad idea, as it means that Arceus takes a huge amount of damage and can no longer sweep effectively due to it being severely weakened and in the range of opposing priority. Setting up on a Pokemon that Arceus-Normal forces out something that is forced out, such as a Pokemon Choice-locked into a choice-locked move that cannot deal much damage to Arceus-Normal, works nicely.
Team Options
========
Primal Groudon absorbs burns for Arceus-Normal, sets up Stealth Rock, and, most importantly, blows almost every Steel-type away with Earthquake, Fire Punch, (comma) or Lava Plume. Again, Dark-types such as Darkrai or Yveltal are appreciated to help deal with Arceus-Ghost, Giratina-Origin, (comma) and Lugia, although, with some luck, Arceus-Normal can break through Arceus-Ghost itself. Mega Gengar can trap checks such as Lugia and severely weakens Arceus-Ghost as well, and it can trap and heavily damage Steel-types that would wall Arceus-Normal, again using with Focus Blast or Hidden Power Fire. Blaziken and or its Mega Evolution trample Steel-types and can weaken Salamence for Arceus-Normal or vice-versa (I don't think you need the dash). Ho-Oh beats up on physical walls, reduces Steel-types to molten slag (nice), and softens Primal Groudon for Arceus-Normal. Palkia is an interesting option, (comma) as it can remove Fire Blast Ferrothorn with Fire Blast, switch into defensive Primal Kyogre, and can also lure in and Thunder Wave support Arceus-Ghost to Thunder Wave it, allowing Arceus-Normal to break through it much more easily, and can also switch in on defensive Primal Kyogre. Xerneas and or Klefki deal with defensive Yveltal, with the former providing a strong offensive presence that scares Giratina-Origin away and, whilst potentially also providing additional cleric support should Arceus-Normal not find a turn to Refresh, and the latter setting up Spikes and spreading paralysis and poison to cripple the opposing team, while also walling Lugia. Lastly, Latias or Latios with Hidden Power Fire can lure in and dispose of Ferrothorn or and Scizor, with Latias again also being able to use Healing Wish to bring Arceus-Normal back for a second go at the opponent's team.
Other Options
########
Extremely niche coverage options such as Dragon Claw, Iron Head, (comma) or Poison Jab can be used for Arceus to break through Giratina-Origin, (Mega) Salamence, and or Unaware Clefable. Choice Band + Trick gives Arceus-Normal an initially stronger Extreme Speed, and lets it potentially cripple certain checks, but the combination leaves it at the mercy of Mega Gengar should it get trapped while locked into an unfavorable move. Wallceus is a defensive set that benefits from Normal's sole weakness to a very uncommon type in Ubers, and it can run moves such as Ice Beam and Earth Power alongside Will-O-Wisp and Recover so that Arceus can KO some of the Pokemon things it is supposed to be checking (do you mean KO some of the Pokemon that Arceus is supposed to be checking, or KO some of the Pokemon that are supposed to be checking Arceus?). A Bold nature and (this part is unrelated to outspeeding Rayquaza, so I'm moving it later in the sentence) 56 Speed EVs should be used to outspeed Adamant Rayquaza, with maximum HP investment and the rest being poured into Defense along with a Bold nature.
Checks & Counters
########
**Arceus-Ghost**: Arceus-Ghost can at worst Speed tie with Arceus-Normal if both are running maximum Speed, lives survives a +2 Shadow Claw, (comma) and cripples Arceus-Normal with Will-O-Wisp. It can falter against Refresh variants, however. Focus Blast Arceus-Ghost is capable of dealing immediate damage to Arceus-Normal as well.
**Defensive Yveltal**: Yveltal lives survives anything except +2 Life Orb Stone Edge, which has a small chance to OHKO from full health and is a guaranteed KO after Stealth Rock. Yveltal can then OHKO back with Black Glasses-boosted Foul Play, or KO with Foul Play after Stealth Rock damage, a round of Rocky Helmet recoil, (comma) or a round of Life Orb recoil.
**Giratina-Origin**: With proper investment, Giratina-Origin can survive be EVed to live a +2 Shadow Claw after Stealth Rock and can either cripple Arceus-Normal with Will-O-Wisp or phaze it with Dragon Tail.
**Lugia**: Lugia is insurmountable if its Multiscale is intact, easily phazing Arceus-Normal away. It can also Roost back to full health to reactivate Multiscale even while taking a +2 Shadow Claw. However, +2 Life Orb Stone Edge can OHKO after Stealth Rock.
**Will-O-Wisp Arceus**: Arceus formes such as Ground and Fairy can take a +2 attack and burn Arceus-Normal with Will-O-Wisp, crippling it. Arceus-Rock resists Extreme Speed but risks losing the Speed tie and getting KOed by +2 Earthquake.
**(Mega) Salamence**: With Intimidate before Mega Evolving pre-mega and huge physical bulk after Mega Evolving post-mega, Salamence can win one-on-one without if Stealth Rock is not on the field, 2HKOing with Return or at worst dealing huge damage with Double-Edge or Return. It falls to Ice Beam or Stone Edge after Stealth Rock damage, however.
**Mega Gengar**: Mega Gengar outspeeds Arceus-Normal and can either heavily damage it with Focus Blast or give its life to take Arceus-Normal down with Destiny Bond. It is outsped and KOed if it has not already Mega Evolved, however.
**Skarmory, Ferrothorn, and & Scizor**: Skarmory completely walls any Arceus variant without a Fire move, phazing it out while barely taking a scratch. Scizor can take a +2 Earthquake relatively easily and deal heavy damage to Arceus-Normal with Superpower. Ferrothorn can deal damage to Arceus with Iron Barbs, can Leech Seed and can Protect to rack up residual damage on Arceus-Normal with Iron Barbs, Leech Seed, and Protect. It does not take +2 Earthquake too well, however. All (was there supposed to be more here?)
**Unaware Clefable**: Unaware Clefable ignores any Swords Dance boosts, takes less than half from Extremespeed, and can slowly stall Arceus-Normal out with either Moonblast or Toxic.
**Choice Scarf Genesect**: Genesect resists Extreme Speed and can either Explode to deal heavy damage with Explosion or revenge kill a very weak Arceus-Normal with a faster Extreme Speed.
