Both the legal Eldrazi Titans would be great additions.

Ulamog, the Infinite Gyre

Kozilek, Butcher of Truth

Extra ramp, if you think you need more:

• Mana Vault

• Thran Dynamo

• Mind Stone

• Hedron Archive, I'd run over Paradise Plume

• Palladium Myr

• Kozilek's Channeler

ArantirTheDestroyer Thanks for the comment! I am already running Palladium Myr, and Hedron Archive, I could swap out Paradise Plume for Thran Dynamo or Kozilek's Channeler. I honestly don't understand how Mana Vault is a good card, it's basically Basalt Monolith with two down sides. It's great that you get 3 mana for 1 cost, but once you tap it, you have to pay 4 to untap it and if you don't you lose 1 health per turn until you do untap it. Idk, it just doesn't make much sense to me. Could you enlighten me?

Sorry, I must've missed the first two. The whole point of Mana Vault is that it's a 1-drop. Plus, there are ways around that untap restriction, like Unwinding Clock or Clock of Omens. All in all, I think it's a good card if you know how to use it.

ArantirTheDestroyer Oh lol yeah I totally didn't even think about untapping it by other means, I have a Clock of Omens, Unwinding Clock, AND a Voltaic Key. Maybe I should get a Mana Vault. I'll look into it, thanks for the suggestion.

BigDrewTheAnimal, here's my own artifact deck, Jori En's Relics. I run it in there, and even if I have to untap it manually, it's usually early-game, when I'm not too big of a threat yet, so I have the luxury of waiting a turn to have my full mana suite active. Plus, EDH is a 40-life format. One damage won't hurt that much, at least for a while.

Believe me, I used to have the same opinion as you towards Mana Vault, but once I started playing it, I never went back! One of the best Turn 1's I ever had was this:

Seat of the Synod -> Sol Ring -> Mana Vault -> Hedron Archive -> Izzet Signet.

ArantirTheDestroyer Thanks for the deck link. I am currently trying to get a Mana Vault and I am trying to get a Kozilek, because I am gonna swap a Kozilek, Butcher of Truth in to command zone and put the Ulamog, the Ceaseless Hunger into other 99. I am also trying to get a Thran Dynamo.

That's is an insane first hand lol. 9 mana available on turn 2?! What!? Sweet dude lol.

It was actually only 5, because I needed to untap the Vault, but then I topdecked a Gilded Lotus. Needless to say, I was set on mana for the rest of the game!

One other thing... Since you have so many artifacts, I personally would find space for a Karn, Silver Golem in your deck, if only because he's a nice alternate win condition. I got a Karn kill last weekend, and I gotta admit, it was fun swinging with a 9/9 Darksteel Forge and a 7/7 Spine of Ish Sah, among others.

ArantirTheDestroyer Oh yeah true lol, I am good at math. I might actually get a Karn, I misunderstood his ability the first time I read it, now it makes more sense and is more appealing. Thanks for the suggestions, I got an Extraplanar Lens today too, so that will help with ramping.
