More opponent reanimates?

May I suggest:
{Grave Betrayal}
{Animate Dead}
{Grimoire of the Dead}
{Whip of Erebos}
{Rise From The Grave}
{Liliana Vess} (maybe swap here for the other Lili since you've already got {Nythos, Shrine to Nyx} and {Caged Sun})

Very nice deck by the way!!! Just wondering, why so much mana ramp? For Geth I assume...

[Shadridium]

Personally if I run necropotence I run {psychosis crawler} with it, but that's personal. I'm off to bed but ill be back with more ideas I have in mine.

[particle]

but doesn't {psychosis crawler} not interact with {necropotence} since it says put into your hand, not draw?

[particle]

and yes i run the ramp for geth so he can steal lots of stuff. i still never feel like i have enough mana. and the other lili is too slow for her ulti and id rather just run real tutors than use her 2nd ability. i should be running tutors but unsure about which ones.

[Shadridium]

If u have the money {demonic tutor}{diabolic tutor}is a good replacement for it if you don't have one. With your mana ramp you could easily run {increasing ambition}

[particle]

but just to confirm, activating {necropotence} shouldn't trigger {psychosis crawler} right?

[Double-O-Scotch]

It inevitably makes psychosis crawler bigger but it won't trigger from {Necropotence}. It's isn't drawing. Cause of the wording, the cards are put into your hand. Not drawn from your library.

[Shadridium]

Right I should have said that, sorry.

Cabal coffers and urborg tomb of yawgmoth

[particle]

{cabal coffers} is definitely something I should have just looking for a cheaper one, along with a {damnation}, but i am wondering why do you recommend {urborg, tomb of the yawgmoth}? i know it is a great card but it seems pretty useless in my deck.

The three colourless mana givers become swamps with the Tomb out.

[particle]

yea i saw that, still doesn't seem to make sense to pay 15 dollars for a card to make three random lands swamps. {nykthos, shrine to nyx} produces way more mana than it would as a swamp, and likewise, {rogue's passage} is also better utilized as a utility land than as a swamp.

[Weldrodson]

The reason for urborg is to abuse swamp walk and to get the most out of cabal coffers and even nightmare
