Quote from MantisRider »Hey, just thought I'd drop my 4 color list here for some critique since there isn't really a thread for this exact deck. It's basically trying to mix the advantages of Grixis Shadow with the advantages of Jund shadow. Snapcaster Mage and Traverse the Ulvenwald in the same deck with thought scour helping to enable them both offers the deck even more toolbox versatility coupled with the same brutal efficiency Death's Shadow is known for.
Keeping Green in the Grixis shell lets me go down to 1 delve threat, replacing the rest with a set of tarmogoyfs that keep our graveyard stocked for turned on Traverses and more flashback options with Snapcaster Mage. The single Tasigur is still a useful inclusion to avoid losing to Surgical Extraction, Snapcaster Surgical Extraction grabbing all our threats, as well as being a threat that can't be fatal pushed.
The downsides to this list are obvious, a less stable mana base (though not as unstable as you'd think) forces us up to 19 lands to fit in all the relevant shocklands with two basics. We also have a slightly worse burn/8 whack matchup as we have less fine control over our life total due to needing to fetch aggressively simply to cast all of our spells. Sure, we do that most of the time anyway, but with burn you want to very carefully manipulate your life total to allow yourself to battle rage them out before they can kill you, mitigating their kill potential with discard spells and in this list stubborn denial. Depending on their hand and my own sometimes I simply don't have the fine control necessary as often as the lists that are much more three color than four. We also miss out on any lilianas mostly due to a lack of room and due to double black not always being a given here.
Let me know what you think of my greedy list, which has top 8'd my last two fnms, as well as a GPT and a Modern Monday at my LGS.
I've been kind of flitting between Grixis and Jund Shadow as well. I've also been looking into a 4 color list similar to yours, although I still haven't tried it at FNM. Just a few comments:
I think the problem with your list is inconsistency. I don't like having 2 Bauble and 3 Street Wraith. Those cards are what give DS decks such powerful consistency and I feel like those should be the last to be shaved. I also don't think that Tasigur is necessary, given that Goyf is almost always bigger in DSJ. The MD Terminate is kind of sketchy too but that could be a meta call. I'm also not sure about committing 4 slots to Thought Scour. It has some great synergy with Snapcaster but I'd rather see a 4th Traverse, 2nd K-Command, Lili, over them.
In my mind, an ideal list would be something like a DSJ splashing Blue purely for Snapcaster. Snapcaster really amps up the grind level by letting you recast all the extremely cheap powerful removal/discard/Traverse spells. The real question is whether we'd rather just have Lili and white SB cards. Blue doesn't really add anything in the sideboard- I'd rather have Lili over Staticaster most of the time and I honestly can't think of anything else useful. On the other hand, White enables you to tutor for Ranger of Eos and silver bullet cards like Canonist/Kataki as well as providing Lingering Souls for grind power.
