You are already getting so much Attack with Swords Dance that a Life Orb's recoil damage is more detrimental than useful, as another opponent with a Priority move (or one that survives the attack) can knock you down to low enough HP that you need to use Recover, and they'd Likely outspeed you. :P
Refresh is better than Recover, because then you can shake off an Burn and heal with Leftovers.
E-Killer Arceus is not worth using without Earthquake; if you don't want to teach it Earthquake, you might as well not transfer it. :P
A Chople Berry halves Fighting Damage, allowing Arceus to survive a OHKO from a Fighting Z-Nuke that would otherwise, well, OHKO you. :P
Also, a side note, if Arceus carries your entire team, then the rest of your team is probably bad and should be replaced or revised. :P
