ok @Epochalyptik i dont get what you mean by plug my deck

It's when you link your deck on other pages in the hopes of soliciting help.

oh ok im sorry then this is the first time I've done that as i just created my deck like an hour ago

can u take a look at my deck and see if you have any suggestions...if you give me a link i'll take a look at one of yours

Thanks for the comments guys!

@Epochalyptik: Black Sun's Zenith was an easy pull. I was with you originally with my thoughts about Ral Zarek , but in this build he has done surprisingly well. His +1 lets me get extra use out my mana rocks for ramp or larger spells while simultaneously tapping down islands or mana rocks for my opponents to take out possible countermagic mana sources. His second ability lets me take out most utility creatures and planeswalkers as well. To make it faster, I've added Tezzeret the Seeker and an artifact land suite for tutoring and ramp. Its been doing very well lately.

@ms: Lands like Arid Mesa help to fetch me thing anything has has 'Mountain' in it, so Volcanic Island , Steam Vents , Badlands , Blood Crypt or even a regular Mountain . Having the fetch lands thins my deck and makes my mana base very consistent.

Personally, I hate the bounce lands like Izzet Boilerworks . They slow you down and if someone tec-edges it, then you're out two mana. It works against me, especially in a control build.

To your other suggestions ms:

• Graven Cairns et al: They're dead cards in opening hands, and I'd rather have cards that don't require colored mana to give me colored mana.

• Obelisk of Grixis : Coalition Relic is superior.

• Tamiyo, the Moon Sage is already in the build. So is Gilded Lotus , and Chromatic Lantern .

• Olivia Voldaren is good but she's an expensive way to steal a creature.

• I don't attack often, and if i do, it's only with Thrax for removal. So Urabrask the Hidden would be a dead card since Thrax already has haste.

• Tibalt, the Fiend-Blooded has no place in this deck. The randomness of his first ability works against me, and his other abilities aren't strong enough or offer no utility.

• Gem of Becoming is too slow

• Doubling Cube is good, but it I'm not feeding X cost spells and requires more than 6 mana in my pool to see any ROI.

• JTMS is stellar in here. I rarely use his ultimate ability, but thats not the goal with him. Being able to mess up tutors, bounce creatures or draw cards is plenty from him.

Thanks for the suggestions and +1 though! I'll be happy to take a look at your deck.

I really like this deck, but I have one question: why not Mimic Vat ? I use it with my Grixis deck and imprint Fleshbag Marauder onto it with Grave Pact and/or High Market . Although, it doesn't seem like you're going for the sacrificing theme, but they're out there now. I also recommend Slave of Bolas due to the sacrificing theme which helps to boost Thraximundar as well. Lastly, because you're using Bitterblossom , you could use Attrition to boost Thraximundar and destroy nonblack creatures. That combined with Grave Pact is pretty powerful. If you want other ideas, you are welcome to look at my Grixis Thraximundar deck: Welcome to the Thraxi Taxi.

Thanks man! I had Mimic Vat in an earlier build, but it was replaced by Kiki-Jiki, Mirror Breaker . It felt like a dead card half the time, and Kiki jiki synergizes with a lot of the deck.

I also used to run Slave of Bolas but its effect is too costly for what this deck tries to do.

Attrition is a good card, but adding it just because I have Bitterblossom would be a bad idea. Bitterblossom is always viable because for blockers for my planes walkers. Adding Attrition could be dead weight if I don't have the former. I do run that combo with Grave Pact in another deck thoug, it is really freaking sweet.

Thank you for the suggestions though!

I really like this deck, and I keep coming back for ideas. Out of curiosity, why did you choose Mercurial Chemister ? I'm assuming for the card draw?

Thanks man! I'm glad to hear its helped. This has been my project for a couple years now and I'm very proud of it.

I chose Mercurial Chemister mostly as a preference pick. Originally I had Arcanis the Omnipotent in the deck, and while he was excellent at what I wanted him to do, he also was very blue-centric and I always seemed to feel like I was playing a U/B deck with him in it (plus Mind Over Matter ). So I added the chemister because of it's red ability and make the deck more fun for me to play, while still keeping it fairly strong.

Looking over the land you have, and the comments I noticed that the topic of fetch lands had been discussed. However, do you find that it gives your opponent(s) a bit of an edge because you're slowly chipping away at your health?Granted EDH is 40 hp and 1 hp per card isn't significant, but I have always wondered.

Not at all. In my experience, life has been my greatest asset. I'd gladly pay life to fix my mana base, draw cards, etc. For example, it's not uncommon for me to rip 10 life away a turn when I have Necropotence and Reliquary Tower out. Games with this deck are usually over by turn 10, so sometimes its inconsequential.

just a small suggestion that might be useful with thrax Geth, Lord of the Vault

Thanks for that, gave me some stuff to think about!

I noticed that you have lots of control in this build and some card removal. Would Sigarda, Host of Herons not pose a problem for this build? Vindicate or Terminate I feel would be useful for a creature like sigarda.

Also you may consider switching Ulamog, the Infinite Gyre with Kozilek, Butcher of Truth as the butcher of truth is 1 less mana to cast and also helps on card draw.

Scrath Vindicate you don't use white

if u want thrax to be a little more useful than Lazav, Dimir Mastermind might help

I played a Thrax deck a while ago and Rogue's Passage was helpful. Death Cloud was a total bomb too.

@ms : In this build, Geth, Lord of the Vault is not ideal. He's an expensive mana dump which doesn't further the purpose of the deck (which is control). Lazav, Dimir Mastermind also doesn't help this deck at all.

@TheAssassinCrab: Things with hexproof can pose a problem. Good thing is that so few creatures in EDH with Hexproof are threatening. Terminate is in the build already. However, I've found that the best way to deal with troublesome Hexproof cards is with Thrax himself. Destroy all the other creatures and then play Thrax for an assassination with his second ability. With Sigarda, she's nothign a good ol' fashioned Damnation can't take care of ;)

To your second suggestion, I do have a Kozy, but it's in another deck :) I use Ulamog mostly as a reset switch anyway. Do you think it would be better to switch them?

@Human_Rogue_21: Rogue's Passage was in an earlier version when I focused on a voltorn strategy. Since I rarely attack now with the deck, it may pose as a dead draw. Your other suggestion, Death Cloud , I love. But it also would have been better suited for an earlier version of the deck when pain and mass sacrifice was more a theme (I used to run Braids, Cabal Minion as well).

I love all these suggestions though guys. Please, keep them coming. This deck has been my pet project for a long time and I want to make it as efficient as possible. Lately I've been toying with more artifacts since their is a lot of synergy in my colors with artifacts. Any thoughts?

Both Eldrazi's have the annihilator 4, and if either card is put into the graveyard you end up shuffling your graveyard into your library. The main difference is the first effect of their text: Ulamog allows you to destroy a specific target, nice one of your instances hasn't dealt with it. Kozy, when casted says to draw 4 cards, I sense a large part of this build is on card draw and I think that ability alone gives it a spot in this deck. Also you will notice the one less colorless mana needed when casting him.

I love the idea of being the player behind this deck and shiver at the thought of playing it, I will be coming back here to help my build on Thrax. Decided a couple days ago to do a second EDH revolving around control!!

True. I rarely cast Ulamog, maybe for that reason that you mentioned ( the built in kill). It could be worth it to spring for another Kozy then to have it in the deck. I'd rather not remove my other one for a swap. I'll playtest and see how it works.

You're right though about the deck. This is THE deck in my playgroup that is the one to beat. My friends groan and moan when I play it because of it's oppressive nature so I only bust it out with them every now and then. But when I'm at my LGS its no holds barred ;) Please, feel free to refer back to it whenever. I love that some of my creations help to inspire other players. Control is a lot of fun when you get it down, definitely worth a build.

but lazav will help control if you have thrax out and if you play alot of multiplayer he is really useful. i just put him in my grixis deck

I would try play testing it a couple times to see how you like it. If this were my current deck I would swap out Ulamog for Kozy because it's ability.

What are you wanting your artifacts to do? Mana related or +/+ type deals? Little more info there would be sweet.

A few things that worked for me in my Thrax deck were: Frost Titan , Mind's Eye , Rhystic Study , Sword of Feast and Famine , and Mystical Tutor .

You could consider Grim Monolith , it is almost identical to Mana Vault might be neat to have em both in the deck if you really wanted to add more possible mana to this build.

@ms : Thats a very small instance. As I mentioned earlier, I RARELY attack with this deck, and if I do, it's for control purposes. Adding Lazav literally does nothing to help promote the purpose of this deck and is too color-saturated for my liking. He may work well in yours but I can't imagine finding a spot for him in this.

@TheAssassinCrab: I like Kozy's ability so I'll definitely give it a shot. Ideally I'd want my artifacts to either ramp, control, or offer some sort of utility. I'm looking at possibly cutting Lotus Bloom for something faster. With all my untap effects, Grim Monolith might be a deserving replacement. I was also thinking Nihil Spellbomb or Relic of Progenitus to add GY hate and expand my Trinket Mage suite.

@Human_Rogue_21: SoFaF would be more beneficial if I attacked often. Good card, not necessarily ideal for the build. I pulled Rhystic Study from an earlier build because I found Mystic Remora to be more useful (My meta pays the additional 1 a lot). I had a Mystical Tutor in here earlier but pulled it for the Diabolic Intent . I may have pulled it too soon though. What do you think of trying that in place again?
