Mastermind's Acquisition Discussion


3 days ago

Trevorlb21 I've decided to cut 1 Field of Ruin to add 1 Demonlord Belzenlok back to the deck. It was between that card, Battle at the Bridge, or Mastermind's Acquisition as a 1 of. As far as Karn, Scion of Urza goes...if I feel like has too long of a shelf life, I just play it on top of him AFTER I activate it for the turn then get a SECOND activation out of the new copy. If you want to see someone get pissed off; there's your trigger. You tick him up, draw cards, then play another copy, tick him down to get the other card. The salt flows out of your opponent as he realizes he's fucked up. That's the aggressive fuck you play with 4 copies of Karn, but I don't expect everyone to want to do that. I do it because it wins me games, and my opponent then looks at Karn like he's satan and he goes after him. When he does that, I simply just steamroll him with other creatures.

Carpet_Bottom - With all the Equipment I would consider splashing for Danitha Capashen, Paragon. I would go up to 3x Blackblade Reforged and change some of the creatures to be more Legendary. Mastermind's Acquisition can be replaced with more removal such as Lightning Strike, Harnessed Lightning, Fatal Push, etc... If you are spending for Siege-Gang Commander, might as well play Glorybringer. Finally, based on your curve, I would play 24, not 22 lands. Drop 1x Mountain and 1x Swamp and add in 4x Canyon Slough, in the event you already have enough mana in play or you need some card draw.

Needs more Rat Colony

With only 6 Relentless Rats you need half of your total number on the battlefield to even make them 4/4s. Most of the time they will be 3 mana 2/2s. You need a critical mass of Relentless Rats--at least 20. If you want to dedicate only a small portion of your deck to the Relentless effect, then Rat Colony is much better; unlike Relentless Rats it benefits from any rat you control, including Marrow-Gnawer's tokens. Pack Rat is also superior if you have many non-Relentless Rats.

Rat Colony is strictly better than Swarm of Rats. It's also generally better than Bog Rats, Carrion Rats, Muck Rats, Nezumi Cutthroat (fear isn't worth a large power loss and "can't block", especially when Marrow-Gnawer provides fear), Pestilence Rats (Rat Colony gets +2/-2 under most conditions and costs 1 less), and Earsplitting Rats (not enough graveyard/discard synergies).

Other suggestions

Tormod's Crypt -> Nihil Spellbomb, Bojuka Bog. You can run Crypt in addition if needed, but I would use these first.

Kitesail -> Bladed Pinions, Fleetfeather Sandals.

Geth's Grimoire -> remove. Only four or so cards in this deck actually cause an opponent to discard. Since you're running Ancient Craving, might as well slot in Ambition's Cost as well.

Nightmare Lash -> Lashwrithe. Or just run both, but Lashwrithe first.

Sword of the Paruns -> Bad Moon, Adaptive Automaton, Hall of Triumph, Vanquisher's Banner, and Obelisk of Urd are all more mana efficient and consistent ways to pump your rats.

Altar's Reap -> Costly Plunder, Night's Whisper, Sign in Blood.

I'm not sure how Shriveling Rot serves the deck.

There are two Cabal Strongholds, so one needs to come out. Cycling lands--Barren Moor, Polluted Mire, and Desert of the Glorified--hedge against land-heavy draws. Some cheap utility/value lands like Zhalfirin Void, Encroaching Wastes, Mystifying Maze, or Temple of the False God might be good over some number of Swamps too.

Phyrexian Tribute -> Scour from Existence, Unstable Obelisk. I know black is bad with artifacts, but there is a reason Phyrexian Tribute is in 55 edh decks, and the other two are in over 5000 each, and it isn't just color restriction. They cover all five permanent types instead of just one, including the equally hard-for-black enchantments. Requiring two creatures to sacrifice, Phyrexian Tribute isn't even always easier to cast, and it's effect is far less flexible.

Speaking of Unstable Obelisk, more mana ramp would be prudent, like Wayfarer's Bauble, Mind Stone, and Commander's Sphere. Bontu's Monument isn't Jet Medallion, but is still worthwhile with 27 creatures.

I don't think there are enough graveyard synergies to make Living Death appropriate.

Night Dealings is slow, does nothing if the battlefield isn't somewhat favorable, can potentially get removed, makes you reveal, and can't get lands. Razaketh's Rite and Mastermind's Acquisition tutor with no fuss. If you want slow, multi-card tutoring, Diabolic Revelation, Demonic Collusion, and Increasing Ambition are reliable options. Although none feature Nezumi in their art.

Curse of Death's Hold is a bit narrow for multiplayer; I'd prefer Ascendant Evincar which will hit more enemy creatures overall while buffing your own and being a 3/3 flier.

Again, I'm going to be one of those people who look at Karn, Scion of Urza and just completely disregard the awesomeness of the deck because of the price.

There are more types of cheap and effective card draw whilst working with your exile theme with Mastermind's Acquisition but also being able to have repeated card draw and not just wasting mana on a one time sorcery. I myself would suggest cards like; razaketh, the foulblooded even though its a bit pricey mana wise, it can constantly push into the late game with its "loose 2 search for a card and put it into your hand." Another one could be Torment of Scarabs . It'll constantly push that takedown every turn. 4 mana seems steppe but once it's played, it burns as long as your opponent doesn't have major enchantment removal. I dont know if you would profit from Ifnir Deadlands but it could be okay to throw in, in place of a swamp or two just to create some diversity.

With that said there are others that just popped into my mind and I'd thought I'd share just to get your input. I'm on the fence about Torgaar, Famine Incarnate seeing as you dont run enough creatures to make it worth while but again, i find this deck sometimes coming up short with the late game play. But then again, i might just not be using the card combos and abilities to their fullest extent.

Jimmy_Chinchila I agree on both counts; Dispossess barely was not included in the board because of it only targeting an artifact. Divest hits both artifacts and creatures, and whatever that does not hit, Lost Legacy removes.

Acute19 I went back and forth on whether to mainboard Torment of Hailfire and ultimately decided that Mastermind's Acquisition is a more flexible option. If I look at the early game, and need a card I'm missing it can fetch anything I want. If I am in the early game and draw a Torment of Hailfire its gonna sit there and do nothing until I have mana adequate to use it. When I do use it, it should be as a finishing move. Is it slower than just main-decking it? Yes. I'm viewing it as less flexible though in times of dire need. I can reach for a Vraska's Contempt or Karn, Scion of Urza to break a deadlock with Mastermind's Acquisition or any other spell / creature I need to even the playing field.

Profet93 on My Other Commander is Cabal Coffers

Hey! +1 from me. I run a mono black deck that runs similar to getting "big black mana" . Feel free to check it out for some ideas. Moving onto the suggestions...

Mirage Mirror Utility. Copy coffers, useful artifact or big dude.

Candelabra of Tawnos - Budget allowing, it untaps coffers and it's various copies. My favorite card.

From what i can tell, you don't have any way to mitigate black's biggest weakness (aside from scour and steel helkite), against artifacts and enchantments. As such, you should add some/all of the following...

Nevinyrral's Disk

Oblivion Stone - For those turns u tutor for a boarwipe and need to use it on the same turn (nev disk doesnt let u since it ETBs tapped)

Ugin, the Spirit Dragon - Similar to the above to, but exile can be crucial (ex: purphurous when it isnt a creature so u can't use ashes to ashes).

Karn Liberated - Targeted exile removal (upgrade to scour)

All Is Dust

There are others but those are my favorite. Should they be unavailable to you due to budget or can't find it, let me know and I'll offer budget replacements that are similar.

Black's strengths are tutors, I feel you should use at least 1 - 2 more to improve consistency

Diabolic Revelation - Since you're ramping hard, might as well find all your wincons (and perhaps a Reliquary Tower as land per turn). Also, ADD RELIQUARY TOWER! You are running necropotence!

Mastermind's Acquisition > Diabolic Tutor

Since you like to win with big X spell (your commander), it would suck if it gets countered. As such, you should DEFINITELY add Imp's Mischief. Using imp's mischief, you can change the target of counterspell to imp's mischief, leaving the original spell (ur commander or whatever) intact. No one suspects it, plus its amazing to use on cards like "TARGET player gets two extra turns" ... I wonder who you will target, haha!

Yawgmoth's Will - Budget permitting

Im curious on your thoughts on Strionic Resonator to copy your ETB effects (namely your commander). Also want your opinion on Rings of Brighthearth to combo with Deserted temple, coffers and a lot of swamps to make infinite mana and win your with commander. Should you go this route, you might want to consider adding a Basalt Monolith as well for infinite colorless mana.

I just built this deck, and then came here to look for win cons and I found this. I am trying blue-black, because it gives you access to Mastermind's Acquisition, with board wipes/counterspells/Torment of Hailfire in the sideboard.This lets you either have a win con or toolbox sideboard which gives you access to counter spells against control, and ways to stabilize the board if you are being run over. It also can tutor for a Paradox Engine or Powerstone Shard if you need it too. Black also gives you access to Contraband Kingpin which helps you with beating mono red and other agro matchups while also smoothing out your draws. because I am playing two colors I have found Gilded Lotus to be very helpful but I understand why you aren't playing it in your build. this deck looks really sweet and I can't wait to try it out.

I see you are 4 cards short. Not sure what your budget is, but I'd add Diabolic Tutor and Mastermind's Acquisition for sure. I'd also add Dark Ritual, Hypnotic Specter and Tendrils of Agony a very brutal combo. I like the idea since you are playing green too to add Path of Discovery. My opinion for what it's worth is you run too many Planeswalkers. Hope this helps. All my suggestions are pretty cheap and will lower your CMC. P.S. I love Torment of Hailfire if they can't stop it, it's game over.
