What's your "on the spot" win condition? While you have a bunch of infinite mana outlets, this isn't in and of itself a wincon. Even if you can get infinite zombies, if you've milled your entire deck then you die before they get a chance to attack.

A lot of Sidisi decks run Kozilek, Butcher of Truth as he forces a reshuffle of your graveyard when you mill yourself. That way you can get infinite zombies while ending up with cards in your library to draw.

You could also run Noxious Revival, letting you put a single card back on top of your library, giving yourself 1 turn to deal infinite combat damage.

Thank you for your interest. This deck does not aim to produce infinite zombies. As soon as I mill Dread Return I sac 3 zombies to flashback Venser, Shaper Savant and use my infinite mana and flicker effects to bounce every single permanent that isn't mine. That wins the game on the spot since noone but me can play any permanents or cast any spells. Since my "infinite" self mill is under my control I never deck myself. Even with Hermit Druid I have 3 basics to ensure I don't kill myself off an activation.

I have never been a fan of eldrazi for sidisi. It backfires so often that it is not worth it. This deck often wins by using Yawgmoth's Will to flashback like 10 to 12 cards the turn I mill most my library. Kozilek would essentially make yw useless and its one of the best cards in the deck. I do like Noxious Revival as it has so many uses and is essentially a "free spell."

Love the list!

Nostalgic Dreams could do some serious work in here. I second the Noxious Revival addition.

Meren of Clan Nel Toth might let you get back some choice pieces on your turn if things aren't going your way or they hated out your combo piece (even though you have a plethora of recursion, id give her a chance)

Bababad: Thank you! Nostalgic Dreams is exactly the type of card this deck was designed to abuse. Being able to discard creatures to recur reanimation for 2 mana is just phenomenal. The double green hurts a bit but it is definitely worth a test run.

As for Meren, she is really powerful but a bit slow to get going. I run very few sac outlets and I kind of view her similarly to The Gitrog Monster, which is only consistently good for Sidisi if built around. The cards I want to reanimate are usually high CC so I feel she would have a low impact unless I made drastic changes to the deck.

Now the hardest part what cards do I cut to make room for some or all of Nostalgic Dreams, Noxious Revival and Toxic Deluge?

Nostalgic Dreams for Notion Thief

Noxious Revival for Regrowth (not directly to hand but that instant and free aspect feel better overall. Yes regrowth is better during a Yawgmoth's Will spam but isn't it win more at that point anyway?)

No idea what to cut for Deluge, but you need to keep your critter count high...maybe something from amongst your instants?

Regrowth could definitely get cut. As for Notion Thief, that little bugger all but wins the game with Windfall and Jace's Archivist and is a great hoser card for draw heavy decks.

My only concern (leading on from the earlier discussion) is that even though you may be able to generate infinite mana or even bounce all permanents, this is still not an actual win conditon.

Typically combo based decks want to be able to win on the spot once they have infintie mana. If yo uwere to add Blue Sun's Zenith or Stroke of Genius, you could use this in conjuction with your infintie mana cards and either Rune-Scarred Demon or Eternal Witness (depending on which draw spell you use) to deck your opponents.

One other option would be to use Reality Shift to exile your opponent's libraries.

I am not a fan of the draw x cards, but reality shift is something I would definitely consider since it is a good removal spell outside the combo.

It works best with Beast Within alongside to guarantee that they have a creature to shift however you can somewhat mitigate that with Forbidden Orchard.

enpc: Thank you for the help. With all the great feedback I have been getting lately the deck is miles ahead of what it used to be.

All good. I love designing combo decks so happy to help.

Hello there Lilbrudder!

I was looking for inspiration for my own Sidisi, Brood Tyrant deck and stumbled upon this great creation. I did have a couple questions for you. How has Hedron Crab played? I feel that if he's not on the battlefield within the first couple of turns he becomes extremely underwhelming and upsetting to draw. You mentioned in your description about being able to win turn 3 or 4 consistently. What kind of opening hands allow for that consistency?

I was actually wondering if you would be willing to help me with my own Sidisi, Brood Tyrant deck. I've actually been having trouble making my deck a little more explosive in the early game. I'm also somewhat upset that the deck isn't as consistent as I'd like. I'm not a fan of infinite combos, but maybe, to make the deck what I want, I should just get over it. Would you be willing to take a look at my deck and let me know of any/all suggestions that you may have? I'd love to hear of any infinite combos and don't worry about budget wit me. If you do, thanks in advance, if you don't then love your deck man. Happy self-milling!

Death isn't a finality. Here's what I mean.

Pheardemons: I am happy to help you with your deck. Just give me a day or so to look it over. I feel for you, Sidisi can be very hard to build around due to her randomness factor. The biggest inprovement I made is when I decided to make Yawgmoth's Will an integral part of the deck and added Dark Ritual and Songs of the Damned to fuel it. This allowed me to be alright with milling noncreature spells and allowed me to win so much easier with random parts.

I have found Hedron Crab to be great, especially with fetchlands. Late game it can also be useful since it essentially doubles or triples sidisi's zombie output and increases the chances you dig for the combo piece or tutor you need to win.

There are far too many paths to victory to explain it all but in general to win by turn 3 or 4 consistently you need fast mana accelerents a graveyard filler and a big reanimation spell. Tutors and mulligans are also key. It also takes a long time to know your deck well enough to always know what card to go for in each situation. If you dont have all the pieces a turn 1-3 reanimated jin gitaxis, core augur can dig you to a win con pretty damn fast. I also like abusing Rune-Scarred Demon and Sidisi, Undead Visiers trigger to dig for wincons.

For acceleration the best turn 1 options are Mana Crypt/Sol Ring or Joraga Treespeaker or a way to get an extra land into play early like Gemstone Caverns, Dryad Arbor + Green Sun's Zenith , or Sakura-Tribe Elder. The extra lands are crucial for turn 2 victories since you will always need at least 3 lands to go infinite with Deadeye Navigator + Peregrine Drake .

For graveyard fillers the best two cards are Hermit Druid and Buried Alive, but other options include Intuition, Entomb, and Survival of the Fittest. Birthing Pod is also essential for getting the right card. Eldritch evolution will be nasty as well.

For big reanimation spells Victimize Living Death and Wake the Dead are the unholy trinity.

As for infinite combos, unless you are playing cutthroat edh, Sidisi really doesnt need them to be effective and win at your LGS. I used to play a token themed reanimator sidisi deck with cards like Grave Titan, Hornet Queen and Craterhoof Behemoth and it was brutal.

I like the deck but I share enpc's concern. I really think you should consider changing your commander to Tasigur, the Golden Fang to make your infinite mana combo a win con.

I see a lot of reanimator decks make use of Necrotic Ooze + Phyrexian Devourer and Triskelion combo. It is devastatingly easy to setup and can probably replace some of the creatures you have here.
