+1 Looks very cool. Love Taurean Mauler in here.

I'd swap out Fire Diamond and Charcoal Diamond for Ruby Medallion and Jet Medallion. They have more usability since they drop the cc of most of your spells, rather than just giving you 1 mana of that color.

Also, Coalition Relic for Coldsteel Heart. Yes it costs 1 more, but you get to chose what color, and can save it for getting 2 mana of any color if you don't immediately need it.

Any Olivia EDH needs at least a few buffs. Blade of the Bloodchief wins games. And of course you can toss in whatever swords of X and Y you own.

Demonic Tutor, Vampiric Tutor, Mana Crypt and Mana Vault are also auto-includes, and I would borderline say Rakdos Charm as well since artifacts are everywhere in EDH. Also, Darksteel Ingot.

The person who mentioned Thran Dynamo was absolutely right. It goes in every EDH deck.

Malicious Affliction rather than doom blade its the same spell but with a morbid ability that copies itself

YamishiTheWickedOne, thanks for the suggestions. Blade of the Bloodchief is on my list of cards to get.

deathkeystroke, great suggestion, thanks!

I forgot Chromatic Lantern

I have a monoblack deck and I have some problems dealing with enchantments. I found that Ulamog, the Ceaseless Hunger, Karn Liberated and Steel Hellkite are good ways of getting rid of them, So I'm suggesting. They are expensive and out fo theme thought, so it's up to you

lil_cheez, I have also noticed that dealing with enchantments is an issue. Thanks for the suggestion.

Why did you remove Demonic Tutor? Diabolic Tutor is a blatant downgrade.

Also have you considered Yawgmoth's Will or Yawgmoth's Bargain?

How about Kalitas, Traitor of Ghet?

Kalitas would have been amazing if his tokens were vamps. He still has potential.

YamishiTheWickedOne, I took out Demonic Tutor strictly because of its cost. I would prefer not to spend more than $10 on any one card.

whatskraken, thanks for the suggestion. Kalitas, Traitor of Ghet will probably end-up in the deck. I am just waiting to see if the price comes down after the set release.

On the sweeper front, a low cost option is Crux of Fate. Blightning might be good just to screw with them too.

abdulbaqr, thanks for the suggestion! I will be making room for Crux of Fate.

freezerboy, regarding your suggestion of Ruby Medallion and Jet Medallion: Can you explain this swap in a bit more detail. What is the difference between reducing spell cost vs adding mana? Why is reducing spell cost better? Maybe I am missing something, but they seem pretty much the same to me.

I would replace Victim of Night with Dismember. You have enough life gain to afford 4 life.

I would also suggest replacing Doom Blade with Ashes to Ashes, for the same reason.

And Diabolic Tutor should be Demonic Tutor just because of the CMC. If it's out of your budget, that's okay :D

TheHelvault, I agree, Ashes to Ashes is better than Doom Blade. As for Dismember though, it's only -5/-5 which doesn't kill all of the big, powerful creatures EDH can include. Then again, it does get around Indestructibility. I will keep it in mind while play testing and figure out if its going to work better for me.

Thanks for the suggestions. I appreciate it!
