Saw a lot of things in your deck, so I gotta ask what you want to accomplish. From all the draw, counter, destroy, and recursion, I'm assuming this is more of a control build than aggro, but what is it that you want to do ultimately?

yes, def. Control!I wanna use his force against himself.I Played once online against a similar deck and had no chance :P

If you're looking to cut things, Augur Spree is pretty bad outside of limited.

Stuff I would cut or replace:

Auger Spree , Conquering Manticore , Clone , Personal Tutor (I don't like it, it's Sorcery only, at sorcery speed and you don't have it already in your hand (Card Disadvantage)). I'd put down your number of Ramping artifact and bring down your curve a bit. 3.63 is a high Avg. CMC for a control shell.

Also Mirrodin's Fastland aren't that great in a singleton format, I'd replace them with better options.

Ok well I will try my best to help, so I will go about this building from the ground up:

1) Ramp. Since you have a 7 costing commander, I'm gonna say getting him out quickly is not going to be an easy task without some ramp cards. Here's all the ramp I suggest you pick from:

• Mana Crypt , Mana Vault , Sol Ring , Grim Monolith , Basalt Monolith , Thran Dynamo , Gilded Lotus , Dimir Signet , Izzet Signet , Rakdos Signet , Chromatic Lantern , Goblin Electromancer , Helm of Awakening , Jet Medallion , Ruby Medallion , Sapphire Medallion , Nightscape Familiar , Stormscape Familiar , and Thunderscape Familiar .

I think that's all the good ones for you, but let me know if I missed something important...

2) Control. Since your commander likes sacrifice abilities, here are all the cards that control through sacrifice:

• Tainted AEther , Syphon Flesh , Fleshbag Marauder , Funeral March , Liliana of the Veil , Pox , Tribute to Hunger , Ashling, the Extinguisher , Barrin's Spite , Barter in Blood , Braids, Cabal Minion , Consuming Vapors , Grave Pact , Retribution , Slum Reaper , Smallpox , Urborg Justice , Warren Weirding , Death Cloud , Geth's Verdict , Gatekeeper of Malakir , Lingering Death , Innocent Blood , Killing Wave , Chainer's Edict , Cruel Edict , Devour Flesh , Diabolic Edict , Far / Away , Undercity Plague , Sheoldred, Whispering One , Ulamog's Crusher , Artisan of Kozilek , Kozilek, Butcher of Truth , Pathrazer of Ulamog , It That Betrays , and Ulamog, the Infinite Gyre .

Sacrifice is obviously the way to go.

3) Recusion. Since a lot of these require you to sacrifice creatures, why not sacrifice creatures that come back? Here are those creatures:

• Gravecrawler , Bloodghast , Nether Traitor , Reassembling Skeleton , Nether Spirit , Skaab Ruinator , Ashen Ghoul , Shirei, Shizo's Caretaker , and Veilborn Ghoul .

4) Draw. Lastly, you should be able to keep your control aspect going by drawing cards throughout the game. Here are things that draw you at least one card per turn:

• Bottled Cloister , Phyrexian Arena , Underworld Connections , Honden of Seeing Winds , Bloodgift Demon , Staff of Nin , and Mind Unbound .

Choose what you like, and ignore what you don't.

To add to the above draw list, Rhystic Study can be pretty awesome.

So good, thank you guys very very much! Goin to edit tomorrow

No problem bro! If you got time, check out some of the decks on my profile.

another potential draw engine Necropotence

You could probably drop Sign in Blood (lackluster in EDH) and about 3 lands due to all your mana rocks.

Gravecrawler seems a little off without a sac engine.

Temporal Mastery will be underwhelming. You could remove it completely, or use a different "take extra turns" effect like Time Stretch or Time Warp .

Would take out mana enhancers that do colorless mana.

What about tamiyo? Would be perfect

Also Teferi, mage of Zhalfir maybe, so that if you play 6 drops and they are countered you arent tappedout.

I think cutting a couple creatures like Shadowmage Infiltrator and Dimir Cutpurse and instead just play Coastal Piracy would work pretty good for you. I know that only cuts 1 card total when you're looking to slim down to 100, but I still think this is a better option.

Yep. Also play negate as a good counter for your deck

Cut Temporal Mastery combo and all the "Card Draw on combat damage" shit, ur right dcarpntr.

will add some better instant speed card draw like Fact or Fiction , Thirst for Knowledge , Jace's Ingenuity . or .... Jace, the Mind Sculptor well, yeah ...

@ RikonVan : i need Colorless cause my Thrax costs 7, and 9 after dying just once. Remember: Tezzeret and Ral Zarek Untap my Mana base

Maybe a 3 Mana Draw Combo with Necropotence , Rhystic Study and Jace Beleren would rule..

almost forgot Phyrexian Arena

I would take out those mana enhancers anyways... Go for corpsedance and Necromancy, you can reanimate even the opponent creatures

Turned it all around, still 4 too many cards..

Divining Top isnt good in here. Think about a gitaxian probe before you play the thrax?

suggest Impulse
