I run a sidisi deck as well and five cards I find to be good are Craterhoof Behemoth, Doubling Season, Parallel Lives, Endless Ranks of the Dead, and Mesmeric Orb. I've also found Thoughtpicker Witch to be very helpful for getting rid of troublesome cards especially since I create so many tokens that I can sacrifice, although that works well for me because cards like Mystical Tutor, Enlightened Tutor, and Worldly Tutor are staples in my playgroup. +1 for using sidisi, it's always interesting to see how other players play the commander you like.

Deathrite Shaman is a good card too if you have it.

Great suggestions man, appreciate it. I have a Parallel Lives, never thought to try it here. Cheers!

Y u no Living Death?

Me not yet hav one :(

Thats fair, Hedron Crab also gets funny. Also, ways to get your dudes back like Genesis and Soul of Innistrad are pretty good, and soul is easily obtainable with him being in standard. Exhume, Animate Dead, Corpse Connoisseur, Entomb, Birthing Pod and company also work wonders in this deck. Granted, I don't know your budget so I'm kind of just spewing good cards but I used to play this general. If you want some other ideas I still have my list up on my profile. Good luck!

Thanks for the suggestions! I ran Soul of Innistrad for a while, just never found myself activating that ability. Maybe I'll give it a second shot...

I've wanted to build Sidisi Zombie EDH but hadn't found a build I truly like. This build however looks like what I was aiming for. How has it played for you? +1

try Mesmeric Orb. it is both self mill and a win con. you can also try Consuming Aberration, it is a monster in any mill deck.

Hey thanks! Yeah Mesmeric Orb looks awesome, I'll have to try and find one to try out :D

Yeah lakais88 this build is super righteous. But also flexible enough to adjust strategy in the face of momentum swings and go BOOM in response! I find it to be a good mix of mill + self mill + massive zombie armies. The key is to pick your moment with which to attack // and or go for a huge mill spell :) If you're thinking about Sidisi as a commander, I highly recommend - sometimes she doesn't feel as 'green' as the mana symbol in her cost suggests, but she is awesome none-the-less.

Love the deck name. It's a fave flavour text. Villainous Wealth is one of my Favourite cards

Ender666666 -- Thanks!! Appreciate it. It's some of my favourite flavour text in the Dragons block.

I can't help but notice that you only have 2 Instants in the deck. Do you find that it slows down or limits your interactions at all? As a blue player, this seems distressing.

Ender666666 I guess that comes from a bit of play testing overtime -- it boils down to whether to focus in on the strategy, or run a plethora of counters/kills, etc, but when I'm putting so much into my graveyard, it feels counter-intuitive to run a full complement of instants when I can zone into the strategy more.

Are there any subtractions you would reccomend for any instants?

I didn't have anything in particular in mind... It was just a general observation
