Yahenni's Expertise Discussion

Ragamander on Blue/Black

The first thing I'll say is that with 21 lands, you probably can't expect to get the mana to launch Army of the Damned or a really powerful Mind Grind or Torment of Hailfire. Well, at least without Organ Harvest, of which you're only sporting one copy. (If you don't play with teammates, or if you don't play with silver-bordered cards, you might replace it with Culling the Weak.) For reference, the math on Army of the Damned is that about 1/3 of your cards are lands = 8/24, meaning you need to survive to turn 17-18 (have seen a total of 24 cards between your opening hand and your draws each turn) to hit that 8th land. That’s a long time in a Magic game.

Second, Mind Grind, while fun, is questionable here, since none of your other cards will mill your opponent. Many people play with 4 copies of many of their cards, so milling them might not cut them off from their game plan unless you mill them so much they might die. And for that, you would need more support for the mill plan or a LOT more mana. (This is possible, but a big change. Look for cards like Glimpse the Unthinkable and Mind Funeral. Otherwise, I'd cut it for cards that affect board-state or life-totals.)

Third, your overall game plan appears to be to stall in the early game for more powerful plays late, since your low cost cards are generally defensive. This means you'll want more lands in your deck so that you don't stumble on your way to those big plays. I'd remove Coral Atoll and put in four Dimir Aqueducts. It's not the ideal play, but it's cheap and there's a lot of upside if your opponent doesn't Ghost Quarter it or something. Anyways, that will take you up to 24 lands AND increase your average mana output a little more, letting you rely on 4CMC, 5CMC, and 6CMC plays to dominate the game.

Finally, on to individual cards:

Kraken Hatchling, Mausoleum Wanderer, Pharika's Chosen, and Will-o'-the-Wisp are all fine defensive one-drops, but they all do something a little different. Thornbow Archer is a little more aggressive than the rest of your deck wants, so maybe drop it and pick your favorite of those first four and add a second.

Fogwalker is okay on defense, though it's not the best two-drop out there. I'm not a fan of Olivia's Dragon, especially outside of madness/reanimator decks. Rancid Rats just doesn't offer enough oomph for the mana (skulk is not typically a very useful ability). Graf Rats is bad unless you have Midnight Scavengers, so it's really about how much you personally want to meld them. Ultimately, I'd rather replace them with better blockers like Wall of Tears, Wall of Souls, Contraband Kingpin, Dragon's Eye Savants, Gifted Aetherborn, or the absolute top-tier Baleful Strix. Other value options include Omenspeaker, Sigiled Starfish, and Augur of Bolas. Other fun options here are Surge Mare, Riptide Mangler, Lazav, the Multifarious, Fathom Feeder, and Ludevic's Test Subject  Flip. Choose your favorites. Alternately, spot-removal like Doom Blade, Victim of Night, Cast Down, Go for the Throat, and sometimes Dimir Charm are pretty effective.

Wharf Infiltrator can be good sometimes. You can leave it in for fun or replace it.

Eternal Scourge has its uses, but I don't think this deck is optimized for it. Ideally you'd want a few things that can exile it from graveyard or hand, such as Gurmag Angler, Soulflayer, Tombstalker, Scavenging Ooze, Grim Lavamancer), Azor's Gateway  Flip (from hand), or the most hilarious option, Serum Powder. As it stands, it's just difficult to kill outside of combat, like a bad shroud or hexproof. Honestly, I don't think you need a 3/3 to be immune to removal. Replace with a finisher, which I'll discuss in a bit. Alternately, one of my favorite defensive 3CMC creatures is Graveblade Marauder, since its offensive capabilities can rapidly increase.

Markov Crusader isn't actually very good even in the rare case when you do have another vampire, and you only have one other one. Compare to 4CMC utility wunderkind Kalitas, Traitor of Ghet, 5CMC finishers (like Archfiend of Depravity, Glyph Keeper, Ob Nixilis, the Fallen, Vengeful Pharaoh, and maybe even Serra Sphinx), and 6CMC game-winners (like Noxious Gearhulk, Dread, Kokusho, the Evening Star, Wurmcoil Engine, Grave Titan, or even Vengeant Vampire, though that last one is much worse than the others). Sure, none do exactly what Markov Crusader does, but some are close and they all have incredible upsides. Even something like Shriekmaw might ultimately gain you more life by just killing something outright, plus it's super-flexible. Heck, Soul Ransom and Mind Control are strong cards too, at least against creature decks. Anyways, Markov Crusader is a card to replace.

Midnight Scavengers is okay, especially if you have a lot of disposable deathtouchers to bring back, but it still doesn't compare favorably to the above finishers unless you really want to meld it with Graf Rats. Remember, doing things you want to do is an important part of MTG. But if you don't care to meld, I'd look to replace it.

Ob Nixilis, Unshackled is fine. In most cases it doesn't compare favorably to the 6CMC critters above, but it has its uses. If you've got a lot of little deathtouchers (Pharika's Chosen, Typhoid Rats, Dire Fleet Poisoner, it can grow really out of hand. Also, Field of Ruin forces a library search.

Elder Deep Fiend is fine. Usually you play it in a deck that has plenty of creatures you don't mind (or are better off) sacrificing (for example, Priest of the Blood Rite, Relentless Dead, Doomed Dissenter, Stormbound Geist/Geralf's Messenger), then you emerge it early and tap down lands. That's not really your plan here, so it's probably not the best choice. Some good choices for replacements are above, but within the category of emerge creatures, I think Distended Mindbender fits your deck better.

Organ Harvest is a powerful card, but has some drawbacks. Most importantly, a lot of people don't play with or against silver-bordered cards. They're not legal in any official tournaments. Tournament legal variations are Dark Ritual, Culling the Weak, and Ashnod's Altar. Other than that, it's a card that is useless in many situations and completely changes what you're able to do when you actually can make use of it, and that can be awkward from a strategy perspective. If you don't have creatures, you can't cast it. If you don't have a big spell in your hand, you don't need to cast it and you'd rather have almost any other card. So it wants your deck to be full of disposable creatures and big spells, like an emerge deck or a zombie deck really making use of Army of the Damned and From Under the Floorboards. But for the most part that is not this deck, so unless you want to build around the card, I'd remove it, either replacing it with Dark Ritual which is always useful when drawn early, or something else that's cheap and effective: Dead Weight, Apathy, Doom Blade, Pharika's Chosen, or whatever.

Sorcerous Sight is worse than Peek and Gitaxian Probe, but I don't think any of those are particularly good in your deck. If you want to know what's in your opponent's hand, play Telepathy. Otherwise, there's better card draw: Preordain and Ponder are the best cheap spells, but it might be worth spending more mana for more effect with Sign in Blood or Chart a Course.

Cemetery Recruitment isn't particularly good with so few zombies. You can add more zombies, or switch to Ghoulcaller's Chant/Find / Finality/Recover/Disturbed Burial/Death Denied to simulate the effect, or just do card advantage the old-fashioned way, with stuff like Sign in Blood/Consult the Necrosages/Read the Bones/Notion Rain/Secrets of the Golden City. Alternately, shred your opponent's hand (and lose friends) with Hymn to Tourach or punch your opponent for cards with Shadowmage Infiltrator. If you're committed to bringing creatures back from the dead, look to Zombify, Extract from Darkness, or Isareth the Awakener, which can randomly run away with the game if your opponent doesn't have an answer. The most efficient reanimation spell is Unburial Rites, but you'd need to splash white for it to be better than the above options.

Contingency Plan doesn't actually net you any cards in hand; you just control what you are going to draw later. Since you're not very graveyard-focused, there's little benefit. The more flexible version is Dimir Charm, and the more powerful version is Lim-Dul's Vault. If you want to stack the top of your deck for 2CMC without wasting a card to do it, there's Diabolic Vision, but the 1CMC Preordain and Ponder are worthy as well. Alternately, raw card advantage is an option. Any of the options I've already listed are fine, but here are some more: Chemister's Insight, Foresee, Deep Analysis.

Mind Grind attacks on an irrelevant axis. Recommend replacing it with a finisher unless you add more mill. If you want a non-creature finisher, Ob Nixilis Reignited is pretty cool. If you just want something that can't get Murdered, there's Sphinx of Jwar Isle.

Torment of Hailfire is possibly workable if you go to 24 lands with Dimir Aqueducts. X=3 is pretty much the bare minimum, and if they have cards in hand even that might not be enough. This is a possible swap for a finisher, as above.

Army of the Damned is hard to cast at 8CMC. Recommend replacing it with a cheaper finisher unless you're all about Organ Harvest.

Apathy is pretty decent at 1CMC. Probably not as good as just casting Doom Blade/Go for the Throat to kill the thing, but definitely more interesting and fun. It can stay in, though swapping it for something more reliable is technically the correct decision.

Strange Augmentation is bad in your deck. While +3/+3 for 1CMC is fine in a very aggressive deck, that doesn't seem like your game plan. Ideally, your finishers are big enough to win without the extra P/T. If they're not, these could be replaced with kill spells to make sure they are.

Tormod's Crypt is useless unless you frequently play against graveyard-based decks. Even then, with only one in the deck, you're in bad shape. I'd swap it for Relic of Progenitus or Sentinel Totem if you really need graveyard hate. If a creature is reliable against those graveyard decks, Deadeye Tracker, Nezumi Graverobber, or Withered Wretch can do some work. Agent of Erebos is another option. If the only things you need to exile are creatures, then Cemetery Reaper, Dimir Doppelganger, and the powerful Kalitas, Traitor of Ghet are options. Otherwise, cheap kill spells, counterspells, or even more expensive exiling removal (e.g. Sever the Bloodline, Silence the Believers) are options. Phyrexian Scriptures is another card I'll mention, just 'cause it does lots of stuff.

Nevinyrral's Disk is pretty good. Go ahead and keep that in there.

Gridlock is okay, but it's basically a Darkness you can use aggressively. I think Sleep is generally better at that. Alternately, if you want a mass-defense spell, Yahenni's Expertise, Languish, and Damnation are the go-to sweepers.

Outwit is way too narrow; most decks don't target players. (The primary exceptions are burn and mill, so if you play against them a lot, it might be fine.) If you want a dollar-cost-effective counterspell in that slot, play Counterspell or MAYBE Dimir Charm for flexibility.

Turn Aside is okay, but mostly outclassed by Dive Down or Counterspell.

Murder is fine. (Card-wise, not morally!) Technically Hero's Downfall is better if you can get one.

Liliana Vess is fine, but she's a little slow. I'm not sure whether she's better or worse in this deck than Jace, Unraveler of Secrets, Ob Nixilis Reignited, Ob Nixilis of the Black Oath, or even Ashiok, Nightmare Weaver. My inclination is that those are stronger as you increase the median quality of the cards in your deck (making Vess's -2 less important).

Here's one inexpensive, somewhat-boring take:

4x Pharika's Chosen

4x Baleful Strix

4x Graveblade Marauder

2x Archfiend of Depravity

2x Glyph Keeper

1x Noxious Gearhulk

1x Ob Nixilis, Unshackled

1x Tetzimoc, Primal Death

1x Silumgar, the Drifting Death

1x Liliana Vess

1x Jace, Unraveler of Secrets

1x Ob Nixilis Reignited

2x Dimir Charm

2x Doom Blade

2x Agony Warp

3x Notion Rain

1x Extract from Darkness

1x Silumgar's Command

1x Profane Command

1x Nevinyrral's Disk

2x Field of Ruin

4x Dimir Aqueduct

9x Island

9x Swamp

That's just one take on the general strategy. Ultimately, (I think) you're playing Dimir Midrange, and so you're looking for about 40% (24) lands, 30% (18) things that keep you alive until you have 4-6 mana, 20% (12) things that kill your opponent and are themselves hard to kill, and 10% (6) things that put you ahead on cards just in case you're not drawing the right part of your deck.

JohnnyCRO on My Zur brings all cards to the yard!

You got your hands on a YagWill? Wow, good job mate!

OK; first thing I'm noticing here is that you're going a lot on the cEDH side here. Is that by design or what? BC our meta is more about creatures and here lagging behind a few turns can have a high cost in life and therefore result in an unsatisfactory performance. Meaning that in lower-power metas, sometimes specific solutions are better than budgeted competitive ones. It's just my experience tho.

Now, about the whole Doomsday plan, you could really use Pact of Negation. After its masters 25 reprint it's cheap enough to grab one, and most protection piles need such free interaction. Foil is also good in Gush piles, but IMO now Pact is cheap enough and simply better outside Doomsday so it's a buck well-spent in my book. But you can cram in both if you wish.

Anguished Unmaking is an excellent removal you might like. It exiles anything for just 3 mana and a bit of life. The flexibility to deal with any stax piece is potent when trying to go off. Vindicate works along the same lines, saving you some life while losing some versatility being sorcery speed. IMO you're generally a bit low on removal. You must be prepared to clear the board more than once and preferably in a way that works well with Zur. My fond suggestion is Yahenni's Expertise as it leaves Zur alive, catches surprisingly many important targets and doesn't cost you tempo as much as other boardwipes do because of its free cast. Drown in Sorrow is worse, but if that saved is that important to you and you can spare x/3's, then I suppose scry 1 is also fine. Toxic Deluge should be your long-term goal tho. At such low cmc and very reasonable color requirement it's a bargain, plus it can act as a larger boardwipe in case you need one.

Along the same lines, Ghostly Prison and Propaganda could be very helpful in our creature-heavy meta.

Ramp and manabase are different beast entirely and IMO you should first tune the rest of the deck before shifting your attention to those

Any cards you might think of excluding?

captainamerica on UB control for the wallet

1 month ago

Snap157, I run Yahenni's Expertise for the same reason other control decks run Wrath of God effects. I need to keep the board clear. If I run any other powerful sweeper in modern it accomplishes the same purpose (I'm not an aggro deck so my creatures don't really matter until I have 0). What do you suggest as a sweeper for this deck?

Snap157 on UB control for the wallet

1x Telepathy allows you to see what is worth countering and will use your spells wisely. Think Twice will benefit you more than Compulsive Research. I'm a little confused as to why you're running Yahenni's Expertise when it would kill your Nightveil Predator. I've found that my best control wincon for casual play is either Manor Gargoyle or Vampire Nighthawk, and i thin you could afford to lose the gearhulk

sabba5600 on Did you say Fleshbag combo?

2 months ago

PlatinumWare I dont see where me having and outlet would work better. The only creature I actually want to die is fleshbag which I can make kill itself.

TypicalTimmy agreed, my opponent getting to keep the fleshbag would end the combo and that would get tricky if I cant draw more fleshbag or a removal. But Night of Souls' Betrayal also kills the bloodartist effect which just makes the combo end true infinite and I get DQ. Since no one is dying and the combo cant stop. Maybe i can sideboard some extra target removal if it becomes a problem. I coul try Yahenni's Expertise if im careful.

Is there any enchant that gives -1 to just my opponents creatures? Probably to much mana to work....

Just hoping i can keep up pressure enough and fast enough it "shouldnt" be necessary. A lot more play testing is needed.

How is Vraska, Golgari Queen doing for you? What do you sac to her ability? I am also interested in the performance of Yahenni's Expertise. I my builds it was always a letdown. I replaced it with Languish

Riptide Laboratory seems odd to me. In my opinion its only good in control vs control Matchups and there it is more important to control what kind of lands your opponent has. Dust Bowl is for me the better fit.

this deck needs more Yahenni's Expertise or Damnation effects, after seeing it in action it just felt like it needed to be more wrath oriented.
