I've got two: The Tabernacle at Pendrell Vale and Life from the Loam.
You can probably guess, Lands is my deck of choice. There is no more immediately powerful effect printed on a land card than Tabernacle (Library is close, but far more restricted in any format but Vintage - even if it wasn't banned). It's resource denial at worst, and Wrath of God every upkeep at best. As for Loam, there's just something really satisfying about how it plays. I love having the ability to dig deeper into my deck than just about any other non-banned card in Magic, on top of the synergies it has with cards like Academy Ruins and the Thespian's Stage/Dark Depths combo. The intricacies of deck design and the huge number of options that it provides -- that's what I love about playing Magic.
I think it's less about which is weaker or stronger, and more about that we now have up to 8 copies of a cheap 5/x flier to attack with. Phantasm wins a significant number of games even though milling them out is the main strategy; doubling the tools for that alternate line of attack is a good thing. In my view it's play both, not either or. Maybe 4 phantasm and 2 or 3 gargoyle if space is an issue or the attacking plan is deemphasized in your build.
Here we go. Jace's Phantasm has a big brother.
Might this shift the deck to primarily win with these two creatures and use mill as primarily disruption and move it to a secondary win con? Does the deck deemphasise certain mill cards and bring in more varied disruption as a consequence?
These are interesting times for UB Mill in Modern.
Edit: I just realised, since I haven't played the deck in so long... It's a great addition to the UB Mill deck in Modern. Might just have to put that one back together.
If your goal is prisony/grindy, look into some artifacts to bolster that gameplan, such as Damping Sphere, Ensnaring Bridge, Defense Grid or even Trinisphere, Pithing Needle, or Thorn of Amethyst as sideboard considerations. Bridge would lend itself to focusing on non-combat wincons like Vortex or retracing burn with Wrenn and Six's emblem.
If you've considered what I have to offer already, feel free to disregard it... If not, I hope this helps with brainstorming. My suggestions will likely take the deck in a different direction than your current list, but as a long-time Legacy Lands player it's the direction I would personally go. A middleground between the following and what you have might be something akin to the old Legacy Aggro Loam lists relying on Tarmogoyf, Knight of the Reliquary, and so on to present a strong offense in combat. If you're willing to explore Naya instead of Jund, Hall of Heliod's Generosity can add resiliency given the enchantment-based wincons that synergize with the engine, and can make dredge decisions less impactful.
Ramunap Excavator and Tireless Tracker are a couple of things you should consider off the bat as both are very powerful and synergize with the Loam engine well.
The primary strength of the Loam engine in Legacy has always been not only breaking card advantage parity but also, perhaps more importantly, land drop parity. Having access to multiple land drops is what makes Ghost Quarter really shine, and allows you to have the resources to really abuse the engine to cast multiple spells or cycle multiple lands per turn or even dredge loam multiple times. Explore, Rites of Flourishing, Azusa, Lost but Seeking, Mina and Denn, Wildborn, Oracle of Mul Daya, and Wayward Swordtooth would all be on my list for testing in a deck trying to really take advantage of the loam engine. Also, Boseiju, Who Shelters All, Bojuka Bog, and other such utility lands can expand your options in a deck that expects to see a lot of lands. Admittedly, breaking land drop parity is much more powerful in Legacy given the lands legal there, but I think the potential advantages are worth investigating in Modern.
Seismic Assault, Molten Vortex, and Living Twister are all worth considering to bolster your wincon options alongside Ayula's Influence as well as act as durable removal.
Other Dredge cards such as Shenanigans and Darkblast may also be valuable, as well as Ancient Grudge, and cards with Retrace such as Flame Jab, Worm Harvest, and depending on your build, Throes of Chaos.
What sliver list do I want to build? At this point I want to learn. What are my options? My pauper list is pretty basic - I don't get to play it very often...
Thanks much for the welcome!
New to Modern slivers, but I play slivers in Pauper.
Why don't I see Aether Vial in any lists in the last few pages?
It seems like a perfect fit in a deck that wants to swarm, and especially in decks without Gemhide or Manaweft can help boost the early game and support the top end if you end up in the later game.
Very curious...
Any chance someone could link the B/R Discord?
Hmm... Lightning Skelemental does feel like it could fit... In my current list, I'd replace two Kalitas with two of them for testing, reducing the mana curve slightly and setting up for a more aggressive early game. I'm not too worried about the mana cost, but double red early while supporting the rest of the deck might be a periodic issue for my current manabase. Given our discard focus, we can make sure we get maximum value from it by pulling responses from their hand ahead of playing it. Three might be the right number if their value is good. Interesting.
Force of Despair feels like a reasonable sideboard card in a meta with swarm decks.
Diabolic Edict is another reasonable option for us to augment our targeted removal.
Yawgmoth, Thran Physician is also a potential upgrade for the Kalitas slot, with the proliferate pumping our planeswalkers and the discard cost for that ability being a way to get Demigods in the bin.
Plague Engineer seems like another valuable tool depending on your meta.
Aria of Flame seems like a decent way to augment our discard spells, especially after they lose value when the opponent has an empty hand. Worth testing.
Planebound Accomplice is interesting, as a potential way to hedge against getting mana screwed.
Endling looks powerful. I've not been a fan of Morphling variants in the past, but this one has the ability to preserve itself along with its versatility.
Overall, the set looks promising for us in my opinion. Lots of testing to be done.
Dirty deeds... done with sheep.
On topic, that sliver is crazy... though, white hasn't really been a staple color in competitive slivers afaik. I'm sure someone will educate me. Makes a ton of sense at rare. Is there enough fixing to support a five color slivers deck in Modern?
Pretty please!
Why one of Mishra's Factory?
I've loved the idea and feel of the Intuition builds for years, but it seems those don't see nearly as much play these days.
