With the power of the Sky Plate, Arceus embodies the power of the heavens themselves, and rides the winds of punishment upon His foes. Tremble like the aspen before His gale. None of Arceus's creations are immune to His mighty tempest, letting Him throw down His Judgment without much hesitation. Though He has many weaknesses in His Zephyrus forme, including the accursed Stealth Rock, the Mighty One also sports immunities to the dreaded Spikes and Toxic Spikes that plague many of the other denizens of Ubers. Brace for impact from this hurricane-wielding Arceus!
Witness Flying Arceus's glorious moveset. The main idea is to use Arceus's fantastic bulk to survive various moves while setting up. To this end, Calm Mind is a given to power up Judgment to respectable sweeping levels, while Recover increases Arceus's longevity further to render 3HKOs useless and set up even more. However, one must not get carried away with this because of the potential for a critical hit, which may put all of the setting up that Arceus has done to waste. A Timid nature is highly recommended to outrun all threats with base 100 Speed or lower, including particularly major threats such as Kyogre, who can smash Arceus otherwise with super effective moves.
As a Flying-type Calm Mind user, the Wind God's main competition for domination of the skies is offensive Calm Mind Lugia. However, Flying Arceus sports an arguably superior stat spread for the job, having about 16.6% more physical bulk and 7.9% more Special Attack than offensive Calm Mind Lugia does, while missing out only on outpacing Garchomp in terms of Speed. Notably, +1 Hidden Power Fighting 2HKOes Mixed Dialga, and Arceus has an extra defensive option in Iron Defense. Finally, Flying Arceus is not weak against Dark- or Ghost-type moves, which Lugia cannot boast.Team Options & Additional Comments >>>
Flying Arceus's other options unfortunately suffer from large disadvantages. In terms of a defensive support set, Flying Arceus's weaknesses leave much to be desired, and this role will probably be filled better by a more defensively advantaged Arceus forme. A physical set with Fly or Aerial Ace is a poor choice because Fly is risky due to taking up two turns, and Aerial Ace is rather weak without multiple Swords Dance boosts. Those looking for a good Swords Dance Arceus should find a different item to attach to it.
Checks and Counters
Flying Arceus does not like Calm Mind wars with most other Ubers, particularly Giratina, Kyogre, Latias, Latios, Lugia, and other Arceus, especially since Thunder, which is super effective and can paralyze, is viable on all of them. If sufficiently weakened, Extreme Killer Arceus "outruns" with its priority ExtremeSpeed and can set up very easily. Other counters depend on Flying Arceus's auxiliary move; without Substitute, Blissey can wall Arceus and inflict it with status, while without Iron Defense, Ho-Oh and Garchomp can outdamage +1 Judgment with their STABs. Without a Fighting- or Ground-type move, Magnezone can wall Arceus and damage it severely with STAB Thunder.
When facing Arceus, it is very important to know the sprite difference between Flying Arceus and the similar-looking Steel Arceus. You absolutely do not want to find yourself using a Ground- or Fighting-type move on Flying Arceus just because you thought it was Steel Arceus.
