Sumwun is right. All of those moves are bad for Arceus. The best Moveset for Arceus is an EX Killer Arceus. This is the set.
Arceus @ Life Orb/Silk Scarf
Ability: Multitype
Evs: 252 Atk / 252 Spe / 4 Hp
Jolly Nature (+Spe, -SpA)
- Shadow Claw
- Swords Dance
- Extreme Speed
- Brick Break/Earthquake
Since Arceus has Base 120 Stats across the board it has Decent bulk to set up a Swords Dance enabling Arceus to Sweep. Silk Scarf Boosts the power of Arceus' Normal type moves and not at the cost of recoil damage unlike Life Orb. Extreme Speed is STAB and it has Priority. Swords Dance raises its Attack to two stages enabling Arceus to Sweep like I said. Shadow Claw hits the ghost types that are immune to Extreme Speed like Giratina along with its boosted critical hit ratio. Brick Break or Earthquake is Coverage against Rock and Steel. Types that wall Arceus' STAB. Brick Break shatters the likes of Light Screen and Reflect or Earthquake has more base power.
Hope this helps :)
