Definitely add Mycosynth Lattice. This will combo with Darksteel Forge to give all of your permanents indestructibility. The deck is a good concept, but Eldrazi are a tough tribe to work with at times.

Oh yeah, I forgot to add Mycosynth. That was definitely a part of the plan, and yeah, Eldrazi as I am figuring out can be difficult but my play style is big creatures that do big things and the Eldrazi are a cool concept to me so I wanted to give it a shot. Thanks for the comment!

Mimic Vat , Voltaic Key , Unwinding Clock, Clock of Omens , Conjurer's Closet , Blinkmoth Urn , and Extraplanar Lens. Make a lot of manna make and make Ulamog, the Ceaseless Hunger enter the battle field as many times as possible.

I play a lot of EDH, although I am still not crystal clear on how exiling works on commanders. If I exile Ulamog, the Ceaseless Hunger doesn't he go back to the command zone? And wouldn't that make it impossible to "un-exile" him? Wouldn't I just have to pay the extra cost of bringing him back out? Which is 2 mana extra if I'm not mistaken?

you can chose where your commander goes so you can choose to put him in exile(This also workers with any zone your commander would enter).

Oh ok lol, thanks for clearing that up. Ok so I want to bring Ulamog back into play as many times as I can? Ulamogs active ability of exiling 2 permanents doesn't trigger on entering the battlefield, it triggers on cast. Exiling and bringing him back multiple times wouldn't do much good, would it?

No your right it is on cast so my bad it doses nothing lol. The mana cards are still fine but you could use Erratic Portal , Belbe's Portal , Urza's Incubator , Bane of Bala Ged , and Conduit of Ruin.

Also Vedalken Orrery

Ashnod's Altar + Dross Scorpion + Myr Turbine + ( Arcbound Crusher and/or Rocket Launcher). Arena of the Ancients( you could abuse this) and Brass Herald are just probably good in your deck.

I think I'll pick up Erratic Portal, Bane of Bala Ged, Conduit of Ruin, Belbe's Portal, and probably Vedalken Orrery Thanks for the suggestions. Looking again at Mycosynth Lattice, it's out of my price range at the moment.

Paradise Plume doesnt do anything since you cant chose de color colorless and i tried my luck at an colorless edh too you should give it a look Blame it on harper

Paradise Plume doesn't just work on you. It says "Whenever A player plays a spell of the chosen color". So, in my case, I have a friend that plays and all color deck and a friend that plays U/R, so when I play Paradise Plume, I would probably pick Blue to be the color, and then every time either of my friends play a Blue card, I get one life, AND I can still use that Blue mana to pay for any general mana costs. (, , , etc.) So, even though I can't choose "Colorless" as a color, I still get tons of health and can use that mana for any general mana costs I want, that's a win-win from where I sit.

I saw your deck too and it's pretty nice. You have some cards that I couldn't afford at this point in time. It seems that your deck is more creature based. This deck, which I haven't finished yet by the way (the rest of the cards are coming in the mail), is more focused on big creatures that do big things and infinite combos. Once I finish this deck I am going to update the description to give a break down of my thought process behind it and what it can do. This deck can win on turn 5 no matter how many people you are playing with if you get lucky with your draws.

zactrixo I wrote an answer to your comment about Paradise Plume above this. Just wanted you to see it and hope it clears up the reason behind using it.
