Have you considered the new political eternal witness; Skullwinder?

I love reanimation decks, and I'm thinking about playing with BUG rather than Esper.

K34: Sultai is arguably the best EDH color combination of all, and it does suit itself to reanimation very nicely :) However, if you want to build dedicated reanimator, I can link you to a few lists made by my friends that are much more reanimator rather than combo.

PlattBonnay: I'm heavily considering it - there's usually one person at the table who'll get less value out of it than me, or I'll win directly off of returning something, or I have an ally who I want to aid. Not sure what to cut, however...What are your thoughts on Corpse Augur? It's almost TOO good: I might lose enough life to kill me late-game.

How about you add in Platinum Emperion? That way you wouldn't have to worry about the loss of life.

That sounds good, which decks are they?

SirFowler: Perhaps - it also makes it harder for someone to kill me while I'm setting up my comboes - but what would I replace for it?

K34: The Mimeoplasm: An Ooze of Its Own is a very good deck that I play against pretty often. Turn 2 Jin Gitaxias is hard to overcome...

I think you could afford to remove a land or 2. I usually only run 36 in my EDH decks. Sometimes less for mono colored decks. Plus, you have plenty of mana producers and retrievers if you can draw a land.

Since you're in blue I dont think that Corpse Augur is where you want to be. You can play things like Mulldrifter that fill that slot without the potential to kill you. I actually cut it from the Meren precon because its not great early game (cant be clamped, costs 4 so it competes with Meren and Sidisi on the curve) and it is dangerous late game. The window in which you want it is too small in my opinion.

Wow, I haven't updated my Sidisi list in like, a coupla months. I'll update mine, then get back to you.

Also, infinite combo in my new one: Krosan Restorer + Bounding Krasis + Havengul Lich + Altar of Dementia mill anyone out.

SwaggyMcSwagglepants: If you don't mind me asking, how does that work? It seems that you need 4 mana to recast Bounding Krasis from your graveyard (1 to pay Havengul Lich's ability each time, and 3 for its mana cost) and barring something like a Karoo land, you only get 3 mana from each untap of the Krosan Restorer.

I might be missing something. And Krosan Restorer is a card I hadn't considered for this deck yet...

My own Sidisi-deck just got updated. If you have 5 minutes I'd appreciate some feedback, especially with the maybeboard in mind:
Milley Cyrus and her Vegetarian Zombies

Rhystic Study, perhaps?

Lightning Greaves Would be a great addition for both it's protection and one of my favorite combos.

Undead Alchemist Great combo-y goodness while milling opponents, was a staple in my EDH dimir mill.

Altar of the Brood Adds crazy value to most milling/bounce combos and can accidentally win games.

Combo mentioned above(I accidentally used this in a deck to win the first time I played it): Having just Altar of the Brood and Undead Alchemist means that all opponents continue to mill until none of them hit creatures. Although the combo can be interrupted with kill spells etc, there are a number of different iterations, such as having Lightning Greaves and Phenax, God of Deception which means the zombies that appear can join in the milling fun, usually replacing themselves, and then equiping Lightning Greaves to a new zombie, rinse repeat. Since you already have Phenax, God of Deception in the deck, I would say that any of these are a decent addition to the decks combos.

Neur0breed: Thanks for taking the time to comment! I've been considering Lightning Greaves for a while now, and I agree it's amazing as both protection and allowing silly shenanigans. But I've struggled to open a slot for it. What would you suggest cutting?

The other cards aren't really useful for the playstyle I want in this deck, since I play against many graveyard-based decks. I don't want to do their job for them, haha! This is the reason that Mesmeric Orb can be a two-edged sword, despite how good of a card it is. My kill combo is primarily mill-based, true, but it does it all at once, not leaving any time for sorcery-speed exploitation of their filled graveyards.

beckhr: I'd love to find space, but what would you suggest cutting? Honestly I need to just bite the bullet and make a sideboard...

River Kelpie, I'm not sure often you are able to take advantage of this, but the deck seems to take more advantage off of self mill than recursion.

Alternatively, it looks like you have a lot of recursion as well as dredge creatures, so maybe one of those pieces could be removed.

I also wanted to suggest Deadbridge Chant as a swap to one of your single target revives. Your play group may be different, however I find that I can get a huge value out of it before it's removed and it is usually one of my favorite early cards to play.

Neur0breed: I agree that River Kelpie is one of the weaker cards in the deck, being somewhat situational; however, I do draw many cards off of it when I cast Victimize, Wake the Dead, or especially Yawgmoth's Will. I'll consider your opinion, however. GY-to-hand recursion, however, is a necessity in this deck to allow the necessary combos to happen, so that can't be cut.

I had Deadbridge Chant in the original version of this deck (though I'm not sure I'd classify it as "early game"; my meta tends to combo-kill T4 without interference). However, it got cut for two reasons: not enough immediate benefit, and it got REALLY irritating counting 50-card graveyards.

@Daedalus19876 I just converted my Vorel of the hull clade deck into a sidisi deck as I never had done graveyard shenanigans before. I really like this deck and it gave me a ton of new ideas (also very importantly budget ideas) to try out. I was also wondering why you don't have smothering abomination in there. I feel its strictly better than sewer nemesis.I will post my deck soon once I have acquired all the cards I need to finish the deck and would like your comments..

sidarthvader: Thanks for your comment! You're right that Smothering Abomination is a great card, but I didn't see enough of a need for it in this deck. This isn't, in theory, a sacrifice-based deck, and Sewer Nemesis is a better reanimation target than Smothering Abomination. Overall, I didn't feel like I would be drawing enough cards to really make it worth including. On the other hand, Sewer Nemesis grows huge really fast (as fast as my graveyard can grow), and can end games when given flying through Wonder, or sacrificed to Jarad, Golgari Lich Lord. I think that both cards are good, but they don't exactly fulfill the same role in a deck. If your deck is built differently than mine, there may be more of a need for Smothering Abomination than for Sewer Nemesis. Tag me when you upload your deck; I'd love to see it!

sidarthvader: However, I don't know why it isn't already in my Meren deck, which is a sacrifice-based deck in which it would fit perfectly! I'll add it there immediately.

How does the Altar of Dementia + (Extractor Demon/Selhoff Occultist) + Sidisi, Brood Tyrant combo work? Do you target yourself with the altar and hope you hit creatures?

The combo works when you have nothing but a card like Guile left in your library since it constantly shuffles itself back into the library and gets milled again.

Oh, thanks :)

HyperSloth: Thank you for answering Srhike for me; I was at the prerelease and hadn't had a chance to check here haha. (Though it is Dread that I use, not Guile.)

For anyone else who's looking at this, a more complete version of the combo is this:

1) Have only Dread in your library.

2) Sacrifice a zombie to Altar of Dementia, targeting yourself.

3) Death trigger from Extractor Demon or Selhoff Occultist happens, point it at either yourself or opponent.

4) Original Altar mill happens, mill Dread, which re-shuffles itself into being the top card of your library.

5) Sidisi gives you a zombie for milling Dread.

If you target yourself in Step 3, you have an interaction that reads, "Sacrifice a creature: Put 2 2/2 black Zombies onto the battlefield", leading to infinite creatures. If you targeted the opponent, you have an arbitrary amount of mill.

It's also worth noting that, with 3 or 4 creatures to sacrifice, Altar of Dementia, Sidisi, Brood Tyrant, and Extractor Demon will usually manage to empty your library even if you still have 60 cards in it.

Oh man, really needs Bitter Ordeal for when the zombie sacrifice gets going

+1 for you sir. I like this list a lot and i might steal it to give it a while :-P
