Alright, let's get into the Arceus forms. Let's start.
Base Stats: 120 HP / 120 Atk / 120 Def / 120 SpA / 120 SpD / 120 Spe
Role: Sweeper / Cleaner / Revenge Killer / Support
The most fearsome of all the Arceus, and for very good reason. Normal Arceus is the only Pokemon in the game aside from the meek Smeargle to receive Swords Dance and STAB ExtremeSpeed, flattening any team that does not run a dedicated check to it. Common revenge killers such as Choice Scarf Palkia and Garchomp are easily brushed aside as ExtremeSpeed flies past them and wipes them out immediately, and coupled with Arceus's fantastic bulk, it's no wonder that this Pokemon is one of the most difficult to revenge kill. When not using Swords Dance, Arceus can effectively use a Calm Mind set, or even use Choice Specs to hit hard right off the bat. Choice Band can be used to abuse ExtremeSpeed further, allowing Arceus to revenge kill many frail threats. If not used offensively, Normal Arceus can act as a wall due to its relative lack of weaknesses and excellent bulk.
Whatevs sig. QC member for OU and Ubers, VM me for a look at your analysis. Just make sure it's good.
Also, if you want me to rate your team (OU/DW OU/Ubers), give me a VM. If I don't rate it, it's either 1) it's so shit it's too much trouble, 2) I'm busy, or 3) the team is fantastic and I have nothing I can suggest to you. You should be able to recognise which one.
