Monkey22 on The Brood

Non-Linear I wanted Aura Shards in the deck as opposed to Harmonic Sliver because I run 14 artifacts and enchantments in the deck and Harmonic Sliver would force me to blow up my utility artifacts and enchantments too, where as Aura Shards lets me only blow up my opponents. I see what you were saying about Heartstone but I prefer Training Grounds because it only costs one mana instead of three and it reduces the cost of every sliver's ability to one instead of two. I think Crypt Sliver vs Clot Sliver is more personal preference, I thought an early game Crypt Sliver might not be as effective because if you only have a few slivers out and they have summoning sickness than it wouldn't do much good. I think there's a good argument for Heart Sliver instead of Blur Sliver but I think Blur works better for the deck because if my oppoents have a sliver deck then Heart Sliver could help them, where as Blur Sliver only helps me.

In regards to adding more infinite combos, I try to stay away from them for the most part because I enjoy playing the game, not just winning the game. My original plans for the deck had Paradox Engine and Intruder Alarm in it but I just wasn't feeling it. I wanted to keep cards that I enjoyed playing and have never played before.

Some of the expensive cards I have in the deck are because they are helpful and provide value, such as The Immortal Sun and Volrath's Stronghold . Some of them are in the deck because I have never played them before and I think they could be good in the deck and fun to play, like Karn Liberated . I completely understand finding cheaper alternate cards but I want this to be my subjectively strongest EDH deck + one of my favs to play.

Thx for the feedback though, and I may consider building an infinite combo Sliver Overlord deck with some of the cards you mentioned.

Alright, I love slivers and this was my first EDH deck. You have nice and expensive cards some of which are redundant. Harmonic Sliver = Aura Shards but better, Training Grounds is a bit redundant because the cost for the queen is only reduced to 1 and Heartstone will give you the same effect. Some of your slivers seem to only be in the deck because it is TRIBAL. This is the biggest mistake for cEDH you need to branch out and pull value from non-slivers. Crypt Sliver is better than Clot Sliver and Heart Sliver is cheaper than Blur Sliver .

If you already own these cards great, if not find cheaper alternatives. Not to be a prude but it seems you just have some expensive cards because you can and not because it is helpful...

An excellent combo you are missing out on is the Paradox Engine or Intruder Alarm

The one thing about Intruder Alarm is the lack of ways to tutor it up. But yeah, I second Intruder Alarm .

Have you considered Intruder Alarm Would be a good way to continuously untap Vanni.

@LVL_666 so took your advice, now running an Intruder Alarm and will be getting a Paradox Engine to double down on the untap shenanigans. Worked super well. Also got a Vampiric Tutor and Demonic Tutor on the way to replace the non land tutoring. I think I am nearly happy with my deck... At least its near the best I can make it lol

ShreddedByCrows on Linvala Stax, Vannifar‘s worst Nightmare

1 week ago

Hey there!

Nice brew, neat idea to counter those clunky and annoying Vannifars!

As smne who played Mono-W Stax for a while, with the amazing Hokori, Dust Drinker at the helm, I'll share with you what thoughts inspire me your sweet Linvala decklist.

(Even if it has already been pointed out before, I wanna say that I also love the Urborg combo. It's unexpectable and freakin' gud!)

Let's start by the beginning: mana fixation. Extraplanar Lens is insane in every monocolored archetype, so it's a quite logic inclusion you made here. Nonetheless, I suggest you to go for Snow-covered lands to synergize better with it - that way you won't give a lift to your opponents playing white.

Pearl Medallion and Sol Ring are basics, nothing really worth to say about it. Thran Dynamo and Worn Powerstone are more debatable. I don't know what is your budget issue, but if you want a competitve list, Mana Crypt , Mana Vault , Grim Monolith , Mind Stone , Everflowing Chalice etc. are all better options. Dynamo and Powerstone aren't bad cards, but they just come after those ones if you really do need a solid ''ramp'' package.

Opal Palace feels badly slow and ineffective in a monocolored stax deck. You won't win the game by taking up the board with your creatures armed of a little +1/+1 counter.

You have notable exclusions in your lands for a mono-white. Eiganjo Castle is the first card that comes through mind. Buried Ruin also is a recursive tool you should consider, even over Inventors' Fair . If you manage to find one, Ancient Tomb has its place there replacing Temple of the False God .

At its final shape, my Hokori decklist was running a powerful Crucible of Worlds package including Wasteland , Strip Mine , Dust Bowl , Flagstones of Trokair , Lotus Vale and City of Traitors . I was up to 39 lands, not counting Maze of Ith .

Now let's jump straight into your gameplan!

So... you're planning to focus your eyes on ruining Vannifar's day. To help with this strategy of being the nasty ''combo killer'' guy, I think you should put in some additional pieces of disruption.

That said, I don't know which Vannifar's version(s) your playgroup perform with. If it's a Thornbite Staff / Intruder Alarm one, things would be easier to calm down and you won't need such a heavy stax package - you'll need more single-target/multi-target removals though. And if it's the other one, certainly the most popular now (and also the most powerful/absurd), based on many shenanigans around the creatures Vannifar brings to the table, you'll need more stax support.

One of the very best cards you could add to stop all those creature-centered combos is Humility . This card is broken, this card is stupid. It even disables etb abilities. The only way your opponent has to go through is to destroy it with a creatureless source / or with a ''casting'' effect (like Ulamog has).

Single-handly, Humility tears apart most of the competitive Vannifar lists. However, based on the fact that it is still fragile to enchantments/permanents removals, you'll have to build a defensive shield for your stuff. Vannifar lists often keep a strong package of cheap permanents' removals in their pocket (like Beast Within for example), so you'll need to play carefully.

There's a lot of different ways you can head in order to reinforce your permanents' presence on the battlefield. A pretty simple and most of the time effective, despite of its ccm, you already included is Avacyn, Angel of Hope . I think you still lack a way to cheat her casting cost out to make her a stable and destructive power house.

Stax ''enchantment'' strategy is imo one of the most viable and solid strategy. With Academy Rector (amazing alongside your High Market ), you'll be able to search the exact piece you need to lock the game in your favor.

Notable stax exclusions :

Other cards to consider :

A bunch of meta depending stax tools :

Cards I'd cut from your list :

  • Martyr's Bond > Slow and unreliable on this brew. As you're not sacrificing any kind of permanent on your own, you'll struggle to get any value out of it outside of a lost political blast deflagrating when the game should already be over. Unless you add in some cards like World Queller , it defenitly doesn't deserve a slot imo.

  • Norn's Annex > 4 life + 3 mana for a worse Ghostly Prison . And I wouldn't even play Ghostly Prison there.

  • Bishop of Rebirth > a lot of people seems to give love to this card recently. However, I personally think it is just a bad inclusion. You spend 5 mana on a understated body and you have to wait a whole turn before getting value out of it IF you are in the researched scenario. There will be times where you have Boots or Greaves on board and this will be an insane mini-Sun Titan, but the situation is too rare to justify its presence.

  • Sublime Archangel > No real interest here. Good creature but doesn't provide anything for the stax strategy.

  • Gift of Immortality / True Conviction > weird ''win con'' heavily situational cards based on creatures. There is some logic behind Gift, but it's just too much of a unreliable idea. True Conviction has nothing to do here... it's 6 mana spend to lose the control on the game. If you're searching for card advantage and a bit of healing, go for the brand new Dawn of Hope (also is a good mana sink).

  • Rout > There are plenty better aoe in W. Wrath of God , Sunscour , Fumigate , Day of Judgment , End Hostilities , etc. If you want the instant option, just run Vedalken Orrery .

  • Blackblade Reforged > intersting alternative win con. Feels slow nonetheless.

  • Emeria Shepherd > too slow for my liking.

  • Whispersilk Cloak > can't understand what this does in a deck full of flyiers and tapping effects.

Finally, as you want to challenge Vannifar, which is a blue deck, you'll need something to deal with the classical Cyclonic Rift . Teferi's Protection is a good solution (and it could also protects you form a lot of various situations / removals / etc.), but I'm sure you can find a lot of other response.

I hope you'll find useful ideas in this comment. Thanks a lot for sharing this, it reminds me good times. Keep up the good work, keep up brewing!
