Have you played with Lim-Dul's Vault? That card is pretty good, probably better than Vampiric Tutor sometimes.

Instantly brought in by the deck name (Got my +1 there.) Loved reading the Categories too.

Thanks! Took me awhile, I appreciate that you like it. I do have to edit some of it with the new Commander rules at some point though.

I've recently become a fan of Polymorphist's Jest. It is particularly good against problematic things with hexproof like Lazav, Dimir Mastermind or indestructible stuff Avacyn, Angel of Hope (or gods).

Thanks for the suggestion! I will take a look at how it works in the deck.

Sudden Spoiling is as good as if not better than Polymorphist's Jest. Love the split second on it!

Well I guess Polymorphist's Jest goes better with Night of Souls' Betrayal. But at that point you're probably running Humility. Otherwise yeah Sudden Spoiling is pretty nice, I have toyed with it in some commander decks. I never noticed it was similar to that other card. I can easily see how that would provide some interesting political plays.

Thanks for the Suggestions guys! I will test out Sudden Spoiling to see how it goes.

I think something all Oloro decks suffer from is any combo deck in EDH. When someone does that, the lifegain effect just becomes completely irrelevant from what I've noticed. I play Mikaeus (unahallowed) as my general and I never lose to Oloro... I would add an answer for these kinds of decks.

That's what Counterspells are for SpookyToe.

SpookyToe, the whole deck is geared towards stopping combo and aggro decks. With cards like Aven Mindcensor and Counterspell, I shouldn't have any problems. It just comes down to knowing when to stop them, and that comes down to the player piloting the deck.

Prophet of Distortion though fairly weak as a one drop would be a great late game card engine allowing multiple draws

Thanks for the suggestion! Prophet won't help as much as you might think late game. At that point your opponents and you are trying to end the game. So 4 mana can still be a hefty investment, on top of the fact that it has to be colorless mana to boot. If its ability was cheaper or even required a color it would be much better. Still thanks for your input, it is greatly appreciated.

Well i noticed Sol Ring and your other various mana rocks now produce the colorless so didnt factor that much. Just barely started to play commander and it was 1v1 so not too familiar with how important the mana would be

That's fine. It is kind of why I elaberated on it a bit. It helps with suggestions in the future as well as helping the people posting get a new perspective they can use elsewhere.

Get Sanguine Bond, then tutor for Sanguine Bond and Exquisite Blood and gain life off Oloro?!?!?!?

Why isn't this a theme/gimmick deck.

@EnsignCheckov Thanks for the suggestion! I mostly don't like the interaction between them and want to win a different way.

@Raz0r_ I don't know why, I'll update it to add it in when I get some more time
