Hello friends! I'm a long-time lurker on this thread and usually more prone to posting on The Source for my Legacy brews, but I'm a long time Grixis Delver player in Modern, and the new Death's Shadow variants have re-invigorated my enthusiasm in brewing and tweaking the deck!
I started off with the stock Ryan Overturf list, but quickly started tweaking it over last week. The deck really wants to go down to 18 lands, and I've also incorporated some Stubborn Denials. This version of the deck really does feel closer to the tempo end of the spectrum than the stock lists.
Similarly, I've just recently started experimenting with a fourth color splash off a single shock, much like what the Jund Shadow lists have been doing for a while. I opted to start by testing green, because I felt the addition of Abrupt Decay was a valuable catch-all answer that covers many bases that Grixis can have trouble dealing with (I may just be biased towards Abrupt Decay however). Additionally, it gives access to Golgari Charm, which is a nice answer to opposing Lingering Souls, while also having a floor of blowing up problem enchantments or regenerating through a Wrath. So far I've tested against Jund, BW Tokens, UR Storm, Abzan, and stock Grixis Delver with encouraging results. I don't have enough data yet to synthesize a real conclusion on the green splash, but I'm working on it. Below is my list, I can't wait to keep tweaking and brewing this iteration of Delver in Modern, easily the most fun I've had in a long time.
Hey man, welcome to the forum! I think I recognize your username from The Source. Anyway, I really like your deck. I was debating over whether we should go classic Grixis Delver (with the Tropical Island) or do something a bit different.
In any case, I think the green splash is fascinating. I know on the Modern Nexus site there was Ashton proposing a heavier green focus with Tarmogoyf - I'm wondering if you're on the right track with Green instead of White.
It's tough because I'm not 100% sure on each. Some games I regret not having a Golgari Charm , other games I wish I had a Ranger to help override my opponent's mana.
So far, I have changed the mainboard minimally after playing about 12 games vs different decks - Abzan, Jund, Death's Shadow Jund, R/G Ponza, U Tron, Scapeshift, and a couple T3 decks.
The biggest change has been the sideboard to alleviate what are IMO this deck's biggest difficulties - enchantments. To this end, I've removed both Lingering Souls and included 1x Fragmentize and 1x Anguished Unmaking. Fragmentize is a nice answer to deal with pretty much every single problem enchantment for us, and Anguished Unmaking has the double duty of dealing with a problem non-land permanent while also advancing our Death's Shadows.
There was certainly some worry, as Jonny_Tempel noted, of us not being able to get Ranger of Eos within a reasonable schedule. While I can confirm that it has happened once, the other time where it's resolved it brought be 1 Delver and 1 Death's Shadow for the ride (I was at 10 life with no other sources of self-damage available) and it proceeded to cause serious issues for my midrange opponent. 12 games isn't enough for me to know for sure.
The one nice thing about Ranger in this deck is that it's easier to recur if it dies due to Snap + Kommand. The 1 maindeck Noxious Revival is placed to allow me to get back a threat or to get back a Godless Shrine that was milled.
The observant among you will notice I cut the Brutality - in my meta there is more midrange and control and big mana. Not a great card there.
Anyway, hope this was informative. I'm very much looking forward to AshtonKutcher and SomeKindofTimeWizard's experience with the green splash.
I wasn't able to get in any games last night due to me running a Shadowrun campaign but should be able to tonight. I'm really excited to try out the Ranger and Lingering Souls and see if they are as good as I'm intuiting them to be.
Grixis Delver and Shadowrun? You are a person of exquisite taste.
I wasn't able to get in any games last night due to me running a Shadowrun campaign but should be able to tonight. I'm really excited to try out the Ranger and see if it's as good as I'm intuiting it to be.
Thanks for sharing Ah, I can see that Godless Shrine is for Ranger against some grindy matchups. It shines for jund, abzan midrange and other non-snapcaster deck, but it definately would be worse towards blue control deck that could get rid everything in late games.
According to my previous decks, I am at like a 75% win rate with Grixis Delver (in its many variations) vs Blue Control. It solely comes down to us having a huge density of must-answer threats as well as a massive amount of efficient counterspells in the form of dispel, countersquall, and the like.
I don't know how Grixis Shadow Delver is going to play vs control, but for sideboarding I'd probably go something like:
+1 Dispel
+3 Countersquall
+1 Liliana, the Last Hope
Countersquall -> Snapcaster Mage, Countersquall is backbreaking. Every game where I've landed a Liliana, the Last Hope vs Control, I've won. She eats enemy Snapcasters, she recurs countered threats, and her ultimate wins on its own.

The death's shadow build of this deck is silly powerful, but I think trying to imitate the jund version is just asking to be playing second best. This deck's strengths come from what the blue offers, in counters, snapcaster and more card selection. If you just want to slam face with efficient creatures, jund is better. I'm still trying to figure out a final build, but enough results have been posted with different builds to know the delver shell with death's shadow has potential.
I played a couple test games last night, and had the most fun I've had playing MtG in a long time. The deck is very strong and brings the beats fast. The Grixis Manabase is already pretty painful so Death's Shadow slots in easily.
When you play using Death's Shadow, the deck turns into more of a tempo build since you're burning down your life really quickly. To that end, I think we could take a page from Monkey Grow and start using 1 or 2 of Stubborn Denial. Think about it - 3 delve threats plus 4 Death's Shadow is a pretty easy way to get it online.
You know what's really rude? Playing a (minimum) Death's Shadow with Stubborn Denial backup.
I agree that DS Jund is a deck with more raw power, but the tempo advantage that blue brings really can't be understated.
Not a bad idea, and a valid point. this helps protect against Path. My question, do i cut 1 Pierce and 1 Leak for 2-Stubborn Denial?

no the maindeck surgical is to fuel life loss for death's shadow.
and the thoughtseize, surgical combo is just good.
I got the life loss part, but I think it also does a really good job of sucking out removal from an opponent's deck. And yes, Thoughtseize + Surgical is a sweet combo. It's a super weak version of the Gitaxian Probe + Cabal Therapy combo in legacy, but I still think it could be pretty good.
One shower thought for this deck: The Jund version sometimes runs a Ranger of Eos in the maindeck or sideboard, and I was thinking - how cool would that be here? Think about it - we have 8 killer one drops in this deck as opposed to DS Jund which only has 4. We'd need to add in a Godless Shrine somewhere, but I'll do some testing and see if it has legs.
For this switch - we'd need to remove the Gurmag Angler, and then add the Ranger. I'd also probably remove the Blood Crypt for a Godless Shrine.
I wasn't able to attend, but there was a Modern 1K near me and the winner had a Grixis Shadow Delver List. From what I heard the meta had Eldrazi, Scapeshift, and a bunch of other pretty tough lists. The winner's list looks very strong, I assume the MD Surgical is to fight vs Path to Exile decks. I want to try Remand in place of the Mana Leak.
Thanks for posting Overturf's list, deathstroke99.
I would probably play at least 1x Dismember mainboard. It seems great here.
Blood Moon in the side could be good too with such a fast clock. Or are 2 basics not enough?
My biggest concern is that this list is just a weaker version of Death's Shadow Jund.
Sure, Grixis gets to play Snapcaster Mage but the deck is not that consistent like DSJ. What's your opinion?
Having tried out Death's Shadow Delver and having played vs DS Jund a lot, here's my take:
DS Delver has the following advantages:
-More card advantage (Snapcaster Mage, Tasigur if he ever gets 4 lands)
-Ability to protect yourself and your creatures against burn and kill spells with countermagic
-More actual creatures than DS Jund so you can better take a hit against Path to Exile decks
Overall, DS Jund is a much more consistent and focused beast whereas DS Delver is pulled in a lot of different directions. But because DS Delver is pulled in a lot of different directions you also have the ability to react better, and you also can play "protect the queen" and you're better suited to drawn-out matches.
That being said, I see myself at a crossroads with Cryptic Delver vs DS Delver. I enjoy both variants in their different ways, but I think DS Delver might be better suited for the current meta. Grixis has always been well positioned against the hyper-linear aggro decks, and although DS Jund is a new beast, we're still favored against it.
Ironically we may find that Grixis Delver is better positioned in the meta than we thought.
The thing with the online meta is that it can sometimes be extremely different than the paper meta. There's a lot of decks that are really easy to test out in MODO than to gather the paper pieces and play it in person. But I've seen a big uptick in a lot of Eldrazi variants, Bushwacker, GB Snek, and Death's Shadow Jund going up in the MTGO meta, and that may translate into paper meta during the next few big events. I'm currently on Anger of the Gods + Damnation as my sweepers of choice, but I may move back to Engineered Explosives. It just feels too slow sometimes, but you could get the same issue with Damnation so I'm not sure which is currently better positioned. And yes, the deck does have a pretty consistent "nut" draw. You'll see a good amount of them in my upcoming video series, unfortunately!
My experience is from playing Cockatrice (I can't be assed to spend $800 on the same cards twice, I'd rather have duals ) and mine is roughly similar to yours. MTGO is probably still more ahead of the curve but I was playing vs Bushwacker after what seemed like a week after Aether Revolt.
Anecdotally, GB Snek and Bushwacker just tear us up. I've won vs GB Snek and Bushwacker only a handful of times (maybe 25%?) and they're hard to interact with, especially Snek, where every card is a must answer and we lack the exile effects to make them lose out on thopter tokens and the like. I realize that Engineered Explosives is slow but it's the best wide ranging answer, only next to Anger of the Gods of which I've put 1 in my sideboard. Might need to be 2, who knows.
All I know is that I feel the deck is getting to the point where it's stretched extremely thin in trying to deal with these decks that happen to have perfect counters to our deck. Snek taxes our threats, Bushwhacker taxes our answers, and Eldrazi Tron just goes over us.
One thing's for certain - people who complain Standard isn't adding to Modern are barking up the wrong tree. Snek and Bushwhacker are only viable because of Aether Revolt. And on the bright side, I'm having a lot of fun with playing with Cryptic Command!
You'll see in my upcoming video how I talk about the fusion of AV + Delver in the same list and I personally didn't like it. I'm glad you had success, 9tailz, but I do like sticking to the more streamlined Delver + Cryptic list, and that's it.
I feel AVs are currently stronger in the sideboard, but that's just my opinion and more of a statement to the overall meta rather than a hard fact. I've been having far more success without AV in the mainboard, as there are some matchups that are really very fast these days that AV is a huge liability. Naya Bushwacker is picking up lots of steam and they can go off as early as Turn 2 and if you don't have Spell Snare, it quickly becomes damage control where a T1 Ancestral is basically dead (whereas at least Delver can block).
It's becoming really tough for Delver in a format in which the most powerful decks are those that are gaining the ability to go super wide as well as super high (Eldrazi Tron/Tron).
I haven't seen a lot of the Bushwhacker deck locally but I expect to see more of it because it's extremely cheap compared to a lot of Modern decks. Hell, I already have a lot of the cards from drafts/packs so I really just need some of the lands and the Goblin Guides. Anger of the Gods or Engineered Explosives is the way to go. The deck has a lot of "nut" hands compared to most decks I've seen.
Deck seems pretty spicy. Interesting that they go for a 3-2 split for Ancestral Vision/Delver of Secrets vs. all-in. I'm not quite sure how I feel about that, considering that Delver is often a T1-3 creature that pressures my opponent rather than a late-game finisher (which is what it feels like with only 2 copies). Looks like they also trim 1 Thought Scour, which I've seen some lists do, but I think it takes away from the potential explosiveness of the deck with powering out delve creatures. I'll definitely test out the list and see how it does. I'm liking the Kalitas, Traitor of Ghet in the sideboard. It's a move that I've been thinking about for quite some time now. Boom // Bust + Goblin Dark-Dwellers is also an interesting choice instead of the classic Fulminator Mage plan, and I wonder how effect it actually was in the important matchups.
Kalitas, Traitor of Ghet is a fantastic sideboard card and I urge anyone with a more grindy metagame to test him out. There's a lot of Abzan Company and other creature based decks where I'm at and he is an absolute beating.
Isn't magma spray just a pure upgrade to pillar of flame since instant speed is better than sorcery? Just trying to help a fellow delver player out. This is a response to Sonnenrad. I'm new to forums.
You're all good, and honestly it's a fair point. As Kyburn points out, I prefer Pillar of Flame because it can still do 2 damage to an opponent whereas Magma Spray can be dead sometimes. I'll be the first to say it's a meta pick and maybe not something that I'd like in a huge tournament.
I play in a very aggro format and decided to jam two Forked bolts into the mainboard. I removed my mainboard Electrolyze and Collective Brutality to make room. Card felt great in my meta. Having access to a tool that can two for one as early as turn 2 felt great and having extra burn damage never hurt. In an open field I probably wouldn't main them but because of the heavy creature aggro decks at my LGS meta they will stay until further notice.
I recently played a game vs another Grixis Delver list that was essentially Corey Burkhart's control list except it had -4 Ancestral Visions and +4 Delver. I managed to win but it was really cool to play against and it felt very powerful. Only reason I won was because of some opponent's misplays.
I have to say, I really liked the Creeping Tar Pit. One of the things that's great about Grixis Delver is each threat you play is a must-answer card. If I do add back in a 20th land, that will definitely be it.

I wasn't able to get in any games last night due to me running a Shadowrun campaign but should be able to tonight. I'm really excited to try out the Ranger and Lingering Souls and see if they are as good as I'm intuiting them to be.
I personally cut the Spell Pierce and 1 Spell Snare for 2 Stubborn Denial. I think that if Stifle was Modern legal this deck would be Tier 1.
I played a couple test games last night, and had the most fun I've had playing MtG in a long time. The deck is very strong and brings the beats fast. The Grixis Manabase is already pretty painful so Death's Shadow slots in easily.

That sideboard is overall fascinating.
You're all good, and honestly it's a fair point. As Kyburn points out, I prefer Pillar of Flame because it can still do 2 damage to an opponent whereas Magma Spray can be dead sometimes. I'll be the first to say it's a meta pick and maybe not something that I'd like in a huge tournament.
Welcome to the forums by the way!
@lmborj I too prefer Molten Rain to Fulminator Mage but overall like Blood Moon the most.
Nice, I have been testing Caleb Durward's Grixis Delver list recently which also includes 2 Forked Bolts in the maindeck. In my meta there has been a resurgence of Abzan CoCo so I now use 2 Pillar of Flame maindeck.
I have to say, I really liked the Creeping Tar Pit. One of the things that's great about Grixis Delver is each threat you play is a must-answer card. If I do add back in a 20th land, that will definitely be it.
