Would Ashnod's Altar be useful here? and you are not allowed to run a colourless deck without All Is Dust, it's the law.

WAH I forgot All Is Dust!
ok, fixed

Ashnod's Altar isn't so useful, because I don't have a strong token production

That's what I assumed about the altar, unless your playgroup has a shit ton of board wipes it's not great in a build lile this... from what I could tell, I'm not amazingly experienced with decks like this.

I've already put Ulamog, the Infinite Gyre on it;)

Previously I used to play Darksteel Colossus, but Ulamog is better on all sides.

Aaand, Touch, I sincerly forgot to build it with Eye of Ugin , because I sold a playset nearly after the modern's ban announcement and the pain was still strong, ahahahaha!

Kozilek, the Great Distortion, Ulamog, the Ceaseless Hunger and Duplicant are very powerful creatures, i think you should play all three of them. Ugin's Construct and Synod Centurion however, are just medium sized vanilla creatures, i don't think they offer enough to justify playing them.
If you need any more ramp, i suggest Mana Crypt, Mana Vault, Ancient Tomb, Basalt Monolith, Worn Powerstone and Sisay's Ring.

Very cool deck! +1. I have one very similar to this that i've recently put together:Alien Invasion

Spatial ContortionSpawning BedEldrazi ConscriptionMirrorpool

Ulamog, the Ceaseless Hunger is interesting for his cast-effect, this deck lacks of removals,I'm actually waiting the price lowering for aquire it

Duplicant is reeeally interesting, it can remove commanders too?

I recently took off Kozilek, the Great Distortion from this deck, because, like Desolation Twin, I think that the effects are not useful enough to justify the cast cost: draw x card, ok, but Menace does not force the opponent to sac his stuff like Annihilator and can be blocked with Fog or Holy Day, The counter-effect requires the exact cc to counter stuff and this make it too situational.

Ancient Tomb and Sisay's Ring are interesting, but I don't like crypt, vault, monolith : their drawbacks seems awful.

About Synod Centurion and Ugin's Construct...yes they are simply medium creatures with honest CC.I'm thinking to some substitutes (the thing is that I'd prefer have some creatures for every mana tile), maybe Summoner's Egg can offer more interesting situations...

Foundry Inspector and Chief of the Foundry maybe?

Too few artifact creatures to make Chief of the Foundry worthwile. Many of the more expensive spells are Eldrazi and not artifacts (including the commander), which Foundry Inspector doesn't help to cast. There are still plenty of artifacts, but i think something like Worn Powerstone is ultimately better as it a great accelerator towards casting Eldrazi and doesn't die as easily.

I'm agree with Emzed, I'd prefer to not give an artifact-orientation to this deck, BUT I'm pretty unsure of Foundry Inspector : to cast my fetch-eggs and ramp-stones earlier sounds sweet :Q___

PS:

Although I know that Worn Powerstone, Mirrorpool, Basalt Monolith, etc., can be very helpful....things without flash that enter on battlefield tapped/doesn't Untap during the untap step give me Pityriasis rosea X,D

I'm going to suggest:Kozilek, the Great DistortionNever underestimate the power of draw especially the deck is trying to ramp as hard as you are you will hopefully be dropping your entire hand relatively quickly and ramping out a terrifyingly huge Titan but if you don't have a way of refilling your hand when someone inevitably finds a way to remove it you will sputter out and die

On the goal of ramping out I would recommend Metalworker (he's no longer banned) and can produce foolishly large amounts of manna

Also you may want to increase your land count as missing when dropped will be very bad

My Kozilek List

I feel Like Us Kozilek players should stick together. please check this out and give me some feed back :)

By the way i feel like you are definitely wrong about Crypt vault and monolith. they are the best rocks in the deck, especially with clock of omens voltaic key and unwinding clock.

OK guys
