I have some suggestions to make!

I would take out:

Contaminated Ground : It only hits one person and does little to affect the millions of mana people have in EDH.

Debtor's Pulpit : There is better things you could be doing with that two mana!

Gift of Orzhova : This Aura does nothing spectacular for you and should be cut for something with more power.

Martial Law : Tapping two creatures on your turn is not very relevant in most EDH games I have played.

Treasury Thrull : paying six mana for something that's a dead card until the next turn + his affect is not even that good.

Odric, Master Tactician : This guy seems bad in edh.

Phylactery Lich : I was defiantly thinking you should stick with a Sacking Tokens/making tokens/Killing all your opponents at the same time kind of thing. He is just a meaty 5/5 that will get one your your artifacts exploded.

Cartel Aristocrat : Only two damage! there is better sac outlets!

Corpse Traders : Can only hit one person! I don't know about the games you play, but usually EDH has way more players then that! Picking on one person can upset people and start a politics problem!

Vampire Nighthawk : Death touch is neat! But this guy is Tiny!

Go for the Throat : In EDH board wipes are better then Single kill cards.

Murder : See Above!

Now I will list things that are AMAZING but you should consider taking out because they will make everyone hate you out of the game after you go infinite/pull shenanigans with them once:

Sorin Markov : He is hilarious! He also plants a huge vendetta Target on your head.

Exquisite Blood : Goes infinite with Vizkopa Guildmage . This is funny but its not a very respectable way to win a game.

Felidar Sovereign : Playing him early on is broken. If the other plays cant get rid of him in one turn its game over. You mine as well have not played at all! Also, any deck builder worth there salt will have an answer for this. So usually he will just eat some removal.

Now for some suggestions! I will try to keep it simple and just give you some ideas ideas:

Board Wipes!: Wrath of God , Damnation , Austere Command , Catastrophe , Plague Wind , Rout , Etc! They can net you massive card advantage.

Random Good Stuff: Mimic Vat , Sensei's Divining Top , Sol Ring , Solemn Simulacrum , Gilded Lotus , Darksteel Ingot , Phyrexian Arena , Mana Vault , Condemn , Weathered Wayfarer

What is the goal of this deck?

To generate loads of tokens, gain some life, destroy some creatures, and widdle down my opponents.

Have you considered focusing it down?
