@Daedalus19876 lol i like that name! @Emzed i agree with taking out consuming aberration and puting in a crypt incursion, and mesmeric orb seems very interesting, but what would you takeout and how many should i put in like 2?

Absolutely +3 or 4 Mesmeric Orb. The card is a powerhouse in EDH, where decks are nearly twice as large. I might cut your walkers for them, since none of them win the game for you instantly. You could also put in Undead Alchemist over Consuming Aberration as a win-con.

Also, Glimpse the Unthinkable is strictly better than Breaking without access to red mana.

@Daedalus19876- Breaking doesn't require red mana, and is third in line as far as the best modern turbo-mill. Glimpse the Unthinkable is rather expensive. Especially for a meta not everyone cares for. I consider Breaking a budget Glimpse, and Mind Sculpt a replacement Breaking.

I second the following suggestions:
Mesmeric Orb should take the place of the Walkers.
Consuming Aberration MUST come out. No haste, and you can use the mana to cast 2 Glimpse/Breaking and a Scour. Bottom line is, it'll never be as useful as you want it to be. Another Visions of Beyond for this. As a turbo-mill hand empties quickly.

Speaking of that, at least one Ensnaring Bridge should be in your sideboard.

My idea would be to perhaps sideboard Spell Pierce, and replace that with Remand. It's not a hard counter, but is indiscriminating as far as spell type and (more importantly) useful even late-game. Because it works well with Mesmeric Orb's ability.
WHY?
Should the player be able to cast the spell again anyway, all the untapping will surely damn them during their upkeep.

@TheSurgeon thanks for the advice! Ensnaring bridge is a good looking card! When should i sideboard it in? And ill take out the aberration and put in another visions!

Ensnaring Bridge is good against all decks that try to attack with creatures, preferably with power 3 or greater. Noble Hierarch (0 power when declared as attacker) and burn spells like Lightning Bolt are solid ways around it, and it can get removed by Abrupt Decay, Kolaghan's Command or Karn Liberated, so it's not at its best when those cards are factors. A deck like Merfolk is probably the weakest to Esnaring Bridge.

Glimpse the Unthinkable is a u/b mill all star!

I feel like Ensnaring Bridge should at least get a side board slot. It's crazy good for defense against aggro, especially since you can drop many of your spells early, diminishing your hand size. If you don't have that much money though, then definitely prioritize Glimpse the Unthinkable.

I think Jace, Memory Adept should replace the other Jace, but I get that a cheap walker with crazy card advantage is very strategic. Why not take advantage of the Jace you have in using Jace's Erasure? Maybe put in some Serum Visions as a sub for the Jace you have in if you put in Jace, Memory Adept.

Jace, Memory Adept is decent, but this deck doesn't really want a 5-drop. Sometimes you don't get to 5 mana (only 22 lands), sometimes you need to be able to keep mana open for interaction, sometimes the opponent has countermagic. That's a lot of scenarios where big Jace is suboptimal.
Jace's Erasure however, is just a bad card. It costs as much mana as Glimpse the Unthinkable, but for it to mill the same amount of cards, a lot of things have to come together. You have to drop it turn 2, draw 10 (!) more cards over the course of the game, and the opponent can't have Abrupt Decay or Nahiri, the Harbinger to remove it before then. Possible, but unlikely, and what if you instead topdeck the card on turn 4 or 5? Glimpse is still great then, but Jaces Erasure is basically blank.

No walkers. They don't work in mill.

Go with turbo mill, it'll do the job. The other cards in the deck keep you alive, and your opponent disrupted. Walkers are too expensive for mill deck. Get another visions of beyond in here, and another counter.

Walkers don't win mill. Period.

Btw, currently a good number of different decks are packing a single Emrakul, the Aeons Torn (thanks to its synergy with Nahiri, the Harbinger), which presents a huge problem for a mill deck. Outside of Leyline of the Void or a splashed Rest in Peace, you will have trouble beating Emrakul, and unfortunately Nahiri can remove those enchantments easily. Surgical Extraction can get rid of Emrakul once it hits the grave, but it might still not be good enough, since the graveyard reshuffle trigger still happens und undoes all your work.
Also, your sideboard absolutely needs an answer to Leyline of Sanctity, that card stops your whole deck from working. Echoing Truth might be okay.

@Emzed thanks for the suggestions, i took them into consideration, as to what i would do against nahiri and other walkers is the Hero's Downfall if they are an issue. Thanks to everyone again for the suggestions this is th deck list im probably going to start play testing again, lmk what you think!

Ravenous Trap, right, that's a good answer to Emrakul, the Aeons Torn. I don't think 3 Hero's Downfall is a good sideboard plan, 3 mana is a lot in Modern, so you only want a very small number of these. I would much rather play a cheaper card like Pithing Needle. Maybe 2 Needle 1 Downfall?

Yeah that would be a good idea @Emzed

there are some good suggestions here. it gives me ideas for my mill deck.

@galvon75 yeah your deck is very similar to mine so i didnt want to give suggestions too much because they would just be to make it like mine. One thing i will say is that the three main power houses so far have been Archive Trap, Visions of Beyond and Mesmeric Orb. Ive started with a Ghost Quarter and two Archive Traps in my opener and absolutly demolished people when you can follow up with the Mesmeric Orb follow up

Personally, I would take out 2x Mind Funeral and one sculpt for the phantasms. You have plenty of mill power, It'll lower your cmc for the deck, and you could take this down to 20 land leaving you room for say 2x MB Darkness?

Hmmm interesting thoughts @TheSurgeon, do you really think moving down to 20 lands is smart though considering the 4 deltas? And if i took it down, what is the reasoning behind darkness (not that i dont like the card or think its bad) also what does the mb before darkness mean lol.

MB = Mainboard.

I run 19 lands in my mill.

Darkness could be more of a sideboard card against aggro, but you can take it down to 20 land take out one funeral, and then put in 3 phantasm.

I like funeral, but the lower cmc, the better, and an alternate wincon is never a bad thing.

Phantasm seems a little risky, you are making cards like Path to Exile and Terminate live, where they would normaly be close to blanks against you (Hedron Crab usually does something solid before it can be killed, so removal doesn't really count there). If you think Phantasm is a good card in your metagame, run it, but i wouldn't call it an auto-include.

I'm with Emzed on this one. While it feels like a sold blocker, it doesn't seem to fit since your ruNing removal. Don't run too far from your archetype, mill. It's a lot like burn, you want to be as fast as possible.

Also, Darkness works with Mesmeric Orb really well when they swing with everything, you darken the board and then they have to untap all that.

I see what youre saying Emzed and thinking about what you said, i agree and feel like i shouldnt run it. Now the question is, should i cut x1 Mind Funeral and one land (probably a Ghost Quarter to add in the Darkness? @TheSurgeon

That's up to your meta. If it's zoo and aggro heavy, yes.if you're running into life loss problems, I would Mainboard another crypt incursion.

Deck testing will tell.

Glimpse the Unthinkable x4 for every mill deck.

@jamesfiek not to sound rude by any means, but the description talks about glims and why it isnt in the deck, at the moment the extra 4 or 5 cards milled isnt worth the 150 dollar upgrade.
