Wheel of Sun and Moon is a nice way to make sure anything that dies gets mixed back into your library to be tutored up again.

Oh, Martyr's Bond would be amazing if you're facing a bunch of sacc decks. You won't be forced to sacrifice stuff, but when anything of yours does for whatever reason each of your oppoents will have to sacrifice a similar permanent . . . which will trigger a Grave Pact or Dictate of Erebos or whatever making the other people besides you sacrifice something else. In a four player game if you have a Martyr's Bond out and there's just one other Grave Pact in play anything you lose could take out another seven permanents they control.

Karmic Justice works similarly, though it only hits one person.

Still, fight fire with fire.

Since you aren't doing much graveyard recursion I'd just run Rest in Peace over Ground Seal. Seal won't protect against non-targeted recursion (Rise of the Dark Realms, Living Death, etc) and once someone disenchants it then it's again back to graveyard playtime. Just exile all the crap with Rest in Peace preventing any and all schenannigans, shutting down stuff like Aethroes, Glissa recursion, etc. Oh yeah, and since it replaces put to a graveyard with an exile effect it won't trigger Grave Pack if Sigarda isn't out for whatever reason :)

Aura of Silence cripples other people (oracle text is all opponents) and if you need to you can sacc it to kill an artifact or enchantment.

Any reason you're running Sunlance over say Swords to Plowshares or Path to Exile? Sunlance won't kill anything indestructible or with a power of 4 where as Swords or Path deal with it all.

If you're swinging for commander damage find a slot for Battle Mastery and Ancestral Mask.

Doesn't Oloro have to be in play to use him to draw?

Crackdown and Mass Calcify are houses in mono-white.

All those white mana symbols would love Nykthos, Shrine to Nyx.

Martial Coup would be another very effective board wipe that stays on theme.

I'd run Return to Dust (or Revoke Existence) over Disenchant. There's just too many Theros gods these days to not run exile effects if possible.

Pearl Medallion would save you a ton of mana.

Both Caged Sun and Extraplanar Lens would be very effective mana doublers

Mind's Eye is going to draw you more cards than Howling Mine without helping everyone else.

I can respect a player who goes theme > power

Sample hands don't take into account actual board state, Marchesa being in the zone because she got StP'ed the second she hit the board because there's no way to protect her, etc.

Like I said I could be wrong, and actually playing it will show things one way or another.

You can only play so many creatures though, especially in a deck with almost no ramp and a fairly steep curve. I only run like 26 in Edric and that's in a deck with insane ramp/aggro. I think with 33 you're going to wind up with a whole lot of turns where you've got creatures sitting in your hand that you can't get onto the board.

Maybe I'm wrong. Playtesting is the best way to find out, but I think you're going to find it's a bit too many.

I'd start with creatures. 33 is a lot, especially since yours are going to be hard to remove.

Obelisk of Grixis costs three mana to make you a R, U or B. Darksteel Ingot costs three mana to make you any color mana, and is indestructible (and costs like thirty cents). At the very least I'd run the Ingot over Obelisk. Ideally I'd run Chromatic Lantern; it costs three, too, makes any color, and it makes every land you have make any color. It's amazing mana fixing on top of tapping for the same mana at the same cost as the Obelisk.

Goblin Bombardment is a decent sacrifice engine, but personally I'd rather run Ashnod's Altar or Greater Gargadon in most situations. I can see arguments for Bombardment, though.

Lightning Bolt is an amazing card in any format not EDH unless you're using it for storm or something. I'd rather just run a Dreadbore if you're using it for removal.

You have no way to deal with problem artifacts and enchantments. Artifacts are easy w/ Vandalblast or Shattering Spree or Shattering Pulse or Crosis's Charm/Rakdos Charm, but for enchantments you're options are either bounce with something like Capsize, theft with Steal Enchantment, or Chaos Warp. I'd find at least a couple ways to deal with all of them or an enchantment deck with Sphere of Safety, token deck with Eldrazi Monument, etc will be untouchable.

Deathreap Ritual can draw an insane amount of cards in multi-player games without tying up a land like Underworld Connections.

Triangle of War can function as another targeted recurring removal like Executioner's Capsule.

Of the cards I suggested all are under ten dollars, and most are under three. I think Caves of Koilos, Bojuka Bog, Ghost Quarter, Thespian's Stage, Unmake, Sever the Bloodline, and Dictate of Erebos are all under a dollar and Isolated Chapel and Martyr's Bond are under two.

I'd find a slot for a Spine of Ish-Shah or a Blood Moon is going to ruin your day.

Grave Pact, Dictate of Erebos and/or Martyr's Bond would probably help a lot cleaning up indestructible stuff you board wipes don't hit. If not those then I'd say one or two targeted exile effects like Unmake or Sever the Bloodline, otherwise Theros gods or stuff like Tajic or Avacyn could be a problem.

IMO you also need one or two ways to target enchantments. At leas where I play everyone is packing Leyline of the Void and Rest in Peace specifically to shut down Aethros decks, and if you playgroup isn't then it won't take long for them to start.

I personally would rather run Isolated Chapel (or Caves of Koilos) than Terramorphic Expanse. Bojuka Bog is always useful, too, as is Strip Mine (or Ghost Quarter if you're being cheap) to eat Mazes of Ith or other problem lands, and I like Thespian's Stage, because someone always has a cool and worth copying. I won more than one game copying someone else's Dark Depths for example.

Nice job on Do or Die, that's a vastly under-utilized card.

Given how many colored mana symbols are in all your permanents Nykthos Shrine to Nyx is probably going to always be a net gain most times you tap it.

Copperline Gorge, Rootbound Crag and Mossfire Valley are sub-five dollar duals that don't slow tempo like Rupture Spire.

Triumph of Ferocity is probably going to be a free card every turn given how big your critters are.

IMO you need one or two more ways to deal with problem artifacts or enchantments. As it stands now short of a Beast Within you're going to have problems with a Dueling Grounds or token deck w/ Eldrazi Monument and Doubling Season. Hull Breach hits two targets for two mana, and Unravel the Aether and Deglamer tuck the target so it can get rid of Theros gods and annoying artifact commanders, etc.

Like it. Thinks I'd consider:

Unmake > Doomblade. Yeah, it costs one more mana, but IMO it's well worth one mana to be able to hit black creatures, exile the creature so it isn't sitting around a graveyard waiting to be reanimated, and hit Theros gods and other indestructible stuff that pops up in EDh (Avacyn, Tajic, etc.)

Vault of the Archangel can be a game-changer.

Lotta white mana symbols would love Nykthos, Shrine to Nyx.

Crackdown can lock down a lot of decks.

You have two copies of Eternal Witness.

Deathreap Ritual is a card drawing machine in Golgari colors.

Well then Fledgling Mawcor or something. Maybe there's something I'm missing but I think in a deck with 11 planeswalkers the absolutely last thing you'd want to do is to give your opponent free ways to remove their loyalty.

There are plenty of times I can see Empyrial Plate being pretty under-whelming.
