This list... Really doesn't do anything for me. Especially with the Colorless Promo Arceus. In a deck that doesn't really spread (the least it snipes for is eighty, enough to sack a Claydol, and the 1-1-1 Ampharos tech isn't worth it), it just doesn't add anything, and that eighty damage can be satisfied by the Fire Arceus. Plus, in spite of its strenuous (as it's called by some) condition, the set's Colorless Arceus is the only efficient way to power up at the time being. Rotom can only get you so far, and you're wasting an attack that gets you two, locked energies from the discard. That's not exactly good, considering you can snatch six energies from the deck for whatever purposes you need with the colorless Arceus, which also thins your deck out significantly.
It seems you have to give up one or the other: draw power or Set-Up speed...
Or do you? Palkia G says 'hi'. Of course, that'd probably be clunky, all the same.
So, anyway, as I've played around with Arceus, I've noticed some things. Your deck article confirmed my thoughts about one thing: People are straying away from the colorless Arceus from the set.
This is likely due the the fact that it is difficult to get six different types of Arceus out and get the proper set-up. However, I have found that running only one of most of the Arceus (Arceuses... Arcei... The exception being the Pantheon [Omnipotence] Level X and the Colorless one, maybe another as well) that you intend on using and about 0-2 energy for each of them (with the exception of Psychic and Electric, assuming you're using the Psychic Bolt Lv. X. You're going to run about three to five of each energy type) will bring surprisingly quick results and can help you set your bench up as early as Turn 2 (Turn 1 if you're really lucky and go second). The only problem is that the amount of Trainers used to get this to work makes your Gengar Match-Up a nightmare, but you have Dark Arceus to retaliate with, if all else fails.
