Thalia Stompy

Shriekmaw doesn't kill a lot of other problematic creatures like Deathrite Shaman or Dark Confidant which is quite critical.

On the other hand vs fatties we have much better tool which calls Big Game Hunter (it's a human) too bad it's more black splash with additional option vs removal (Madness for B). Side note it's not "may" so be carefully :-).

Other red options are
Fire Imp
Pardic Arsonist
Inferno Titan

Titan is for sure overcosted for this deck (but is best removal), Fire Imp can't deal with any fattie and Pardic Arsonist is conditonal and works only in midgame/endgame. I still think black splash has more options.

I only mentioned Shriekmaw, because he is better than Kavu (can't kill Gofy/Angler/Smasher/Knight etc.) in most cases.

Overall if you need (or want) non conditional removal you must look at White: Swords/Path or (if Chalice matters) Declaration in Stone (Sorcery, but hit ~99% of relevant creatures) all other stuff like Warping Wail, Dismember, Blessed Alliance etc. will only hit "some" targets.

Creature wise besides Shriekmaw, Kavu white also offers stuff like: Banishing Priest, C.Priest+Displacer Combo, or Palace Jailer - white stuff is less conditional but needs more Mana/Color etc.

To stay in color and in stompy manabase, what about Banishing Light or Oblivion Ring?

The deck has plenty of disenchant targets anyway, and if they remove the enchantment they're not removing something else of relevant

Shriekmaw is probably pushing it at 5 mana to get real value out of it, and black doesn't really offer a ton of other things that you need. Palace Jailer was something I considered, but it seems a touch risky.

8 Thalia feels pretty nutty, and I wouldn't drop those numbers. The one-two punch of sticking both Thalias on successive turns was devastating.

Also, here is some video content.

Seeing Medea's exploration of splash options with Kavu along with MD.Ghosts light black splash makes me want to try this...

Creatures: (25)
4 Thalia, Guardian of Thraben
4 Phyrexian Revoker
3 Thalia, Heretic Cathar
4 Thought-Knot Seer
3 Eldrazi Displacer
3 Reality Smasher
2 Sanctum Prelate
2 Shriekmaw

Non-Creature Spells: (10)
4 Chalice of the Void
3 Lotus Petal
2 Dismember
1 Warping Wail

Lands: (25)
4 Ancient Tomb
4 Eldrazi Temple
4 Wasteland
4 Cavern of Souls
4 Caves of Koilos
4 Scrubland
1 Karakas

Sideboard: (15)
3 Rest in Peace
2 Containment Priest
2 Disenchant
2 Stoneforge Mystic
2 Mindbreak Trap
2 Orzhov Pontiff
1 Batterskull
1 Umezawa's Jitte

We have black lands for both Shriekmaw and Pontiff, and have boosted the white lands to what I feel is a now comfortable number for main-decking Sanctum Prelate.

I feel there's some unexplored other options with the black splash. Dark Confidant (though I'm sure we'd have to trim Smasher, or perhaps just SB him)? Mardu Strike Leader? I'm sure there's a few interesting creatures we can Cavern out.

I also like the idea of the red splash (because who doesn't like a Flametongue Kavu) and I feel this gives us cards like Sudden Demise as viable sweeper effects too (since mono-white has a lack of these). Of course, having these sweepers Cavernable (like Pontiff) may just be better, but it's nonetheless a nice option. We can also look at Pia and Kiran Nalaar as a viable bomb in the deck too!

Exciting times ahead, I guess, with now three variants:
- MonoWhite
- Wb
- Wr
Coming about. Wg with Sylvan Library could be pretty neat too.

Nonetheless, the core seems like it's really establishing itself.

Edit: P&K Nalaar with Displacer sounds delicious, I will have to brew a list.

Do you think it's worth it to splash Red for just 4 Kavu and Wear/Tear?

If your using him as a sudo removal spell, I guess I could see it.

I dunno, I guess I'm not sold yet.

I found the deck struggled in many midrange matchups (Shardless, etc.) and having in-built 2-for-1s like Kavu/Shriekmaw is pretty impressive. That being said, Splicer was pretty reasonable for me in MonoWhite, so I can understand your argument that these trumps may be unnecessary. I think, per usual, splashes offer some upsides due to just diversification into effects mono-white does not have (and certainly seem at least doable) but a more fragile mana base is certainly something to consider.

Testing shall tell, and I don't think there's any harm in doing so, but in the end, I think MonoWhite is still an excellent choice.

Edit: Been thinking more about the red version. And came to this:


Creatures: (26)
4 Thalia, Guardian of Thraben
3 Phyrexian Revoker
3 Thalia, Heretic Cathar
4 Thought-Knot Seer
4 Eldrazi Displacer
4 Recruiter of the Guard
1 Pia and Kiran Nalaar
1 Flametongue Kavu
1 Eldrazi Obligator
1 Sanctum Prelate

Non-Creature Spells: (9)
4 Chalice of the Void
3 Lotus Petal
2 Dismember

Lands: (25)
4 Battlefield Forge
4 Plateau
4 Cavern of Souls
4 Ancient Tomb
4 Eldrazi Temple
2 Karakas
3 Wasteland

Sideboard: (15)
3 Rest in Peace
2 Mindbreak Trap
2 Stoneforge Mystic
2 Sudden Demise
1 Containment Priest
1 Disenchant
1 Cunning Sparkmage
1 Manic Vandal
1 Batterskull
1 Umezawa's Jitte

Sideboard feels like the biggest work in progress.

I've been toting a Dragon Stompy version recently that abused 4 Imperial Recruiters as a consistency engine for a deck that is well-known for its high-variance. It played a typical prison core and tried to minimise its one-ofs as much as possible, and used Recruiter more as flood protection and a card to play into the endgame to get bombs such as Pia and Kiran Nalaar or Goblin Rabblemaster.

The same principle is applied here. Basically, we sacrifice the end game beef of Smasher for a toolbox of creatures, most of which are incredibly synergistic with Eldrazi Displacer (which is really finding the best shell for itself here). The rest of the deck is just the usual core of "lock" pieces in Thalias, Seers, Revoker and Chalice. Pia and Kiran Nalaar looks similar in terms of its bombiness to Smasher, but grinds much stronger against decks like Shardless BUG, especially when paired with Displacer.

The same idea can be applied to all the versions I feel (black can give us a toolbox of Shriekmaw, Pontiff etc.) though I feel the red cards are more generally synergistic.

I'm kind of excited by this.

Yes both cards can work (since 2W is nearly perfect for White Stompy) BUT: Abrupt Decay and Wear//Tear are common cards and good against this deck. I would avoid "instant" comeback solutions vs BGx and Miracle Decks. Even against DnT, Flickerwisp is a card so O-Ring isn't a save solution. CC2 of Disenchant also is better if you play with or against Thalia (Thorn/Golem).

Thanks for the Video!

Shriekmaw is not only 5 Mana. Yes, as a creature it cost 1 more than Kavu for more or less the same effect - BUT: it is castable with Evoke for 1B which means Turn1-2 playable if needed as early Removal. With Eldrazi Temple and Displacer it can also be a "4 Lands" play (like Kavu) since you can Evoke for 2 Lands and Flicker with 2 Lands which means: 2 killed Dudes from Opponent and you have a 3/3 and 3/2 (with evasion) on the field.

Mix in Pontiff (this deck needs him vs DnT) and the Black Splash is much better.

@Build:
Before you go down to 3 Displacer i would cut the 3rd Smasher, because this build is more made for cc3 to operate well enough and Displacer simply is really strong here.

@Recruiter
Not sold on him yet. Yes it's nice to flicker around with Displacer but, Recruiter overall is a very slow play and this deck is not as controllish as DnT. You wan't fast lockdown and beats before your opponent can stabilize. Both, Lodestone and Smasher builds are working this way, Lodestone is more Lockdown and Smasher is more fast beats. Recruiter tends to be slow, the same is true for Stoneforge and Equipment. I like Stoneforge but you invest some turns before you can profit.

@Splashes:

Red: I am not sold on red yet: Yes Kavu might be nice but i feel black is stronger (Shriekmaw + Pontiff) and if you need 4cc Removal Palace Jailer (or even Banishing Priest) should be better as Kavu.
Pia and Kiran Nalaar looks nice, but RR is harder than WW (and Prelate is no easy fit, see first pages) and for flickering Dudes Blade Splicer should be strong enough. Yes P+K can do more if they hit the field, but the price is not low with: 4cc and RR - I think they are better at Imperial Taxes. Best fit would be Magus of the Moon as a supprise vs BUG/Aggro Loam/Lands/12 Post etc . but with Cavern+Mox you can also play Magus at Side with Mono W (like Pontiff). Sudden Demise seems nice but it will not work well vs DnT or Mentor with your own white creatures.

Black: Shriekmaw + Pontiff (but Pontiff works well at Mono W if you play Moxes over Petal)

Green: Reclamation Sage + Sylvan Library both are nice but Library overall is "slow" and can't beat and sadly (for this deck) Sage is not a Human and under a Blood Moon it should be hard if you don't have basic forest avaible (Mono White with 5 Plains, 4 Moxes and "Instant Solutions" like Disenchant are much better prepared vs Moon etc.)

Conclusion: I would stay more or less Mono White (with Pontiff Side), because it prevents one common Angel of Attack vs Eldrazi/Stompy decks (Land Hate: Moon&Wasteland Lock etc.) - Manabase (for a stompy deck) is very stable. If you need Removal on a stick you can play Palace Jailer, or if you fear "Monarch" Banishing Priest or the combo of Containment Priest and Displacer. Overall i would avoid too much "DnT" here (maybe that is also true for Prelate!) because the Meta will adjust and you don't wan't to lose vs Massacre/Dread of Night/Sulfur Elemental/Pyroclasm etc.

This is what I am testing against a lot. One key is having 6+ Removal postboard without removing too many (at best none of your) threats (creatures). Reg. Removal: For me that is 2 Declaration in Stone, 2 StoP, 2 Palace Jailer and what I find is really good against midrange decks: Winter Orb (and against Shardless RiP). If you can play it at the right time maybe follow it up with a Prelate on 2 or bait out Decay earlier it is meant to stay and buy you time to punch through their line of defense. Winter Orb of course comes with a sacrifice specifically to lower the number of Smashers you play postboard. Actually boarding is quite complicated and I am still figuring out the right configuration. What for sure goes out in postboard games is Chalice, so there are already 4 free slots. Also Revokers can be reduces in numbers as they basically hit Lilly only considering that RiP shuts down Deathrite. Then it depends on your build what else can be taken out.

I've found P&K pretty comfortable to cast in testing atm actually, as we have 15 red sources (including Caverns). I think the more WW (or RR cards) you include though bias you much more towards Diamond over Petal (for a sturdy coloured mana source). And I also think it's really the perfect card in this deck to go over the top, grinding out midrange strategies with Karakas looping it and it having synergy with our small artifact subtheme. In fact I think this shell is better than Imperial Taxes for P&K, due to the high density of Sol Lands and Displacer.

I think a lot of the other tutor targets I have in the deck are pretty janky though, and I think a card that can be easily castable when flooding on Sol Lands (Endless One, maybe?) could be pretty nice. Magus seems neat... But I think we'll lock ourself out more often. -.-

I also think Recruiter of the Guard, indeed, is a bit slow, but I think shines most in the red version as the quality of tutor targets is pretty high (P&K being foremost). It's really doing what Smasher does (close out the game) but in a very different way, by getting the precision tool we need for the given situation.

That being said, I still think the tried-and-proven white list is the best thing to be doing at the moment, until we figure out how the splashes should really function.

Achievement unlocked killing Progenitus from Elves by Blessed Alliance and TNN from Stoneblade same day :-)

I changed in my list -1 Lodestone Golem, -1 Smasher, +1 Blade Splicer, +1 Eldrazi Displacer.

More bad but good, but idk, ideas.

Creatures: (25)
4 Dark Confidant
4 Eldrazi Displacer
4 Thalia, Guardian of Thraben
3 Thalia, Heretic Cathar
4 Thought-Knot Seer
2 Sanctum Prelate
2 Shriekmaw
2 Kambal, Consult of Allocation

Non-Creature Spells: (10)
4 Chalice of the Void
3 Mox Diamond
2 Umezawa's Jitte
1 Dismember

Lands: (25)
4 Ancient Tomb
4 Eldrazi Temple
4 Cavern of Souls
4 Caves of Koilos
4 Scrubland
3 Wasteland
2 Karakas

Sideboard: (15)
3 Rest in Peace
2 Containment Priest
2 Disenchant
2 Stoneforge Mystic
2 Mindbreak Trap
2 Orzhov Pontiff
1 Dismember
1 Batterskull

4c Loam has all showed us how threatening a turn one Dark Confidant can be, especially when defended by Chalice or, in this case, Sanctum Prelate. He's also typically uncounterable. He certainly lets our deck grind a bit better, but of course, our mana curve is as high as hell and can certainly shoot us in the foot (flipping Seer is... pretty painful) and we're already taking damage with Sol Lands (and in this case, pain lands too). Maybe a shell not abusing our Eldrazi friends may be a better way to go, but idk. Deadguy Stompy certainly sounds cool. For black splashing versions, Kambal, Consult of Allocation is also pretty nice. Giving us a nice pile of hatebears while also being somewhat relevant vs. fair matchups (he certainly is vaguely synergistic with Bob too) makes him an interesting contender.

Anyway, just some thoughts.

I do not think Kambal is the right direction to go. If the plan is to lock someone out of casting spells, I think his total effect will be minimal once that plan is in action. While good on his own, his power is somewhat reduced when you think of the shell overall.

Good points; I guess he's more suitable to a shell that soft locks (where you opponent trying to push out of the lock will trigger him and make him valuable) rather than hard lock the opponent (what this deck is essentially trying to do). My main thought by including him is that since this deck is incredibly aggressive (more so than say, normal D&T) the reach he provides seemed useful. Add some life gain that this lists surprisingly appreciate, and we're cooking. But you're right, he may just be too weak overall in the shell.

Gonna run this tomorrow...


4x Thalia, Guardian of Thraben
1x Thalia, Heretic Cathar
3x Eldrazi Displacer
2x Blade Splicer
3x Lodestone Golem
4x Thought-Knot Seer

4x Sphere of Resistance
4x Chalice of the Void
3x Crucible of Worlds
4x Mox Diamond
3x Smokestack

3x Plains
2x Flagstones of Trokair
2x Karakas
2x Horizon Canopy
3x Wasteland
3x City of Traitors
4x Ancient Tomb
4x Cavern of Souls
1x Miren, the Moaning Well
1x Gods' Eye, Gate to the Reikai


Looking for a turn one "something" and the SB will probably have 3x thorn of amethyst and a trinisphere to swap out for the spheres.
After I play this for a few matches I'll be able to see if I can switch some numbers and even get a mishra's factory or two into the list.
I will probably have phyrexian revokers somewhere in the 75

EDIT:
So i went a disappointing 2-2 and lost to omnishow and burn.
each loss, my opponent had the perfect number of cards and lands to beat multiple tax effects.

the cards that did nothing were smokestack and crucible.
there is too much "tax" on the board for these cards to land early enough in the game to have the needed impact.

if i was to try this deck again, i would change the mana base into black/white for dark confidant and orzhov pontiff.
and for giggles i can play guardian beast!
possible turn one plays: chalice, sphere, thalia or dark confidant: seems good

Guys, Palace Jailer is the nuts. I mean, like, the crazy nuts. In any deck that plays Ancient Tombs and white mana sources, you need to be playing this guy.

I'd love to hear more about your experience with Palace Jailer, MGB. Could you provide some context on the matchups and situations in which it seemed promising?

I read a few pages of the Soldier Stompy deck. Do you think Thalia Stompy or Soldier Stompy gets a bigger boost from Palace Jailer?

---

MGB is right, Palace Jailer is very good. See discussing us over Kavu/Shriekmaw for nearly the same cc but other colors (and creatures für Cavern). Palace Jailer will not have a good Body but will exile all from Delver over Strix, Gofy till Grisel (yesterday I got him vs Show and Tell).

First me and Nekrataal searched for more Removal and Planeswalker cards (SB slots for Shardless, Miracle etc). Test games showed Jailer was good enough going from 1 to 2 SB slots, i switched most games my Lodestone Golem with him so now I finally I test him as a 2off MD. He is good on it's own (even if it is only for card draw).

I got one game vs Blade and my Thalias can't pass a TNN I resolvt Jailer and my opponent had the choice of let me draw 2 cards a turn or attacking with TNN for Monarch, i won this game because I still draw enough cards and every counter Attack was harder for him since TNN alone is not really a game ender. Another game I got finally Displacer + Jailer online vs DnT and it was bonkers.

So yes Jailer is good enough to test. He is better at Soldiers (profit from all Tribal stuff) but this build can abuse him as well with fast Stompy mana, Cavern for Humans and Displacer Action.

Second conclusion about Jailer:

This card has inner risky factor, specially in Aggro/Midrange matchups, for example I wouldn't side them in vs U/R delver - sure it can exile delver (for 4cc so not so good), but losing Monarch can be abyssal if opponent can chump our attacks (smasher is really necessary here).

Scenarios:
1) So this card can give an edge if matchup is tide (not a lot of creatures on table), you remove their only thread so you basically do 3 for 1 (1 for Exiled creature, 1 for Monach endstep, and for sure 1 for Monarch next endstep).

2) If you has less creature (1 for Exiled creature, 1 for monarch endstep) so it's still 2 for 1, but things can get nasty when opponent attacks with enough blockers, now he has +1 CA each turn until you get advantage.

Solider Stompy has much more chumpblokers (like W Recruiter, tokens etc) so the second scenario has lesser probability to occur.

Since I didnt count Jailer itself 2/2 bear so it can be even 4 for 1 which is probably enough risk to handle for me to run them :-)

Yes Jailer (and i think that is the "fear of monarch" effect) has a risk, but we must ask ourself: Is it still better than cards like Kavu/Shriekmaw in the situation or for the task "Removal on legs"?

Scenario 1: You remove the only thread (and we have a lot of spicy ones like Gofy/Strix/Delver till Emrakul) and continue the beats with early Thalia(s), TKS etc. This deck wants to take advantage from stompy/fast mana, so you simply outplay your opponent or forbit to play with you thanks to Taxes stuff or backbreaking effects like early Thalia 2.0.

---

Since one of the goal shut be: "don't fold in the same situations that are bad for colorless eldrazi" like: Facing Strix/Gofy/Delver/Blood Moon because we wan't to play with White Cards to gain advantage over the pure colorless stuff) The deck shut be able to have a way better BGx (mostly Shardless) matchup etc. Thalia & co are here to simply play stronger cards. (Thalia 1.0 is a thorn on legs, manabase is able to use Wastelands better and don't fold to enemy Manadenial thanks to lower cc, mox mana etc.)

---

Scenario 2 is generally bad because something went wrong with the game plan. So you are behind because it means your opponent still has +1 Creature than you. It can only be "ok" if you opponent aims to become monarch and attack with all of his creatures and you can take advantage (if you have more than the Jailer) to block (remember lot of first strikers) and have the possibility for counterattack. If you are way behind on the field (for example facing 3 gofy etc.), the game is more or less over. Yes casting Jailer now may be not good enough but the same is true for every other card in that slot. It basically means your only out is stuff like "All is Dust" and i think we all agree this card isn't good enough for this deck, heck even colorless eldrazi only use it as a sideboard card.

Conclusion: A pair of Palace Jailer shut be ok as a maindeck choice - if they are to risky (since you can't fire and forget) there's always the possibility to play a common removal spell.

EDIT: For the deck name: "(The) Beauty and the Beast" which means "Thalia & Eldrazi"
