RolledAOne

I actually have a list that uses this combo. I would recommend something more defensive and/or alternatively wincons.

Really think you need to have 4 of each of your combo artifacts. A couple of buddies and me have been working on it. here is my take on it, no sideboard yet.

Like I said you should really be running 4 altars and 4 coatings for sure. Green seems a lot better than black for this type of deck too.

I didn't read the other comments but have you considered Elder Deep-Fiend? Now you can't evolution into it and get the tap 4 targets but it's still a good finisher to have in my opinion. You can still use the emerge for two blue if you dont have an evolution in hand. (Assuming you sac a hooting or angler). Also having a 1 of Alchemist Refuge could be spicy for you. Be good late game to flash in a hooting or angler or even an evolution. Also I say Tasigur could be better than angler. I saw someone mention it. It cost 1 less and have a good ability. Sure you won't be able to get Iona but then you could remove her instead and replace her with and fatty or as I said an Elder. Most likely go for 3/4 hootings and 2/3 Tasigurs.

Golgari Charm would be good for you to in the side. All choices can be relevant. You also might want to run a couple damnation or languish for mass removal.

My point excatly. It's not that it is terrible people want to play cheap decks but anyone who wants feedback on something more competitive isn't going to find any help here. This site is just known for kitchen table and budget decks now. Most of the competitive and serious players have moved on to places that will help them improve.

I believe this place has been dead for a while. Majority of the popular decks are all "budget" decks. I just like to use vault as an easy way to share my deck lists but unless you are budget you won't see any views.

I'm not saying you shouldn't play Gaddock but you should edit your description is all. Don't want to give people wrong information. You might want to have like 1 Godless Shrine and 1 Overgrown Tomb. If you plan on playing vs eldrazi a lot your life is important. Kitchen Finks is also useful.

I'm not a fan of building a whole deck to strictly beat another deck. However I should point out that Gaddock stops noncreature spells. He isn't gonna be of use in the eldrazi matches.

I would honestly recommend you drop those Plowbeasts and Day's Undoing for a couple of Pale Recluse (good fatty and helps with mana issues) and maybe run 1 more Demonic Dread. Also Kolgahan's Command has been doing good for me as a 2-of in my deck.

Sorry it's 6 lands. Close enough haha.

Not often but it is there. Normally activate Mindslaver once and you can put some hurt on your opponent. I also run 1 Trinket Mage (MB and SB reasons) and 1 Fabricate MB. So it is possible to make it happen but I don't go out of my way to make it happen. You can get twelve mana with just an island, ruins, tron set + extra tower. So 5 lands?

I think you should really update this list. This just seems like a very stock list that you can find in a primer over at MTGSalvation. I like to play blue tron also and tweak it all the time. Ugin is an excellent choice to add over Karn in my opinion. Karn you want out fast and very early but we are playing control. We won't always get tron assembled by turn 3 or 4 reliable (like you said it is home in a faster tron list).
I cut the Sims, 1 tally, and honestly go down to 1 or 2 mages. Cyclonic Rift is a neat card to use and dismember is also good with tally or without them even. Amp up the lands to 24 or you can take out all tallies and just gorgeous 25 lands.

Well thought out and you know how the deck deals with little speed bumps.

I'd recommend adding in some creatures that give Mimeo some protection and or haste.
Silumgar
Gaea's Revenge
Jodah's Avenger
Just a few that I like to use in my deck.

Are you talking about the cards CMC? It's only 4 colorless and he has no 4 drops in the deck.

I would agree that you should just buy at least two of them. You can get them pretty cheap (5 to 6 each).

Are you asking if Melira and persist work?

Yes it would because if Melira is already out and when your persist creatures come back they can't have the -1/-1 placed on them because of Melira's effect.

Changed it to Gravepurge instead of Congregation at Dawn.

Also what about adding in Gravepurge instead of Congregation at Dawn? It only cost us a black and 2 at instant speed (instead of a solid 2 green and 1 white), puts cards on top of our library and draws us a card afterword. I think this might be better because we can then sac and lose our creatures early game and not feel so bad.

I am with you. That is about how I would run my modern company deck. A few different cards but along those lines. Having more 1 and 2 ofs gives us more freedom to add in answers. I think I would still run Congregation at Dawn but Chord of Calling seems nice too.

I would maybe have another sac outlet.

Falkenrath Aristocrat: not the best choice. You would have to add in red mana source and has 4 CMC so company can't hit it.

Cartel Aristocrat: This is more up our alley. You are running white and black mana sources. Company can hit. It is able to protect it's self for the most part. You can even swing with it if need to.
