Destroyerbirb on K'rrik Son of Yawgmoth 2.0

2 weeks ago

For cuts I would recommend:

Professor Onyx - While Liliana's side job is beneficial for society (educators are very important, especially those who help us raise people from the dead), the deck doesn't have a strong spell slinger theme so her static doesnt work, the minus three is not as optimal as it makes itself out to be, and other effects are... not worth the six mana and time required.

Charcoal Diamond - You've got a ridiculous amount of ramp in this deck already, not sure this piece is needed. Plus, with the way K'rrik, Son of Yawgmoth works, you want to ramp in colourless more than in black with your artifacts and similar since K'rrik, Son of Yawgmoth always pays for black anyways, so Mind Stone just makes Charcoal Diamond look that much more of a downgrade.

Defense Grid - Not really seeing the point. Plus, this is meant to be a casual deck, all this will do is make everyone more upset and make interaction harder.

Saw in Half - It's a fun card not really worth adding.

Meathook Massacre 2 - I have a feeling it's a bit redundant to have both, especially since they both do a bit different things and you've got many tutors. Cutting the second part instead of its original installation would make more sense because this copy does cost a lot for its effect, whereas The Meathook Massacre became so played because it being pretty low costing for everything it does.

Paradise Plume - A lot of mana for its effect, and you have too many ramp cards.

Shared Trauma - Not too sure on this card's inclusion and what it would do.

Chain of Smog - I personally don't think discard cards are very strong in EDH, might be a good cut. I can see this being played against CEDH players and having a big effect, but EDH? Not as convinced.

Grim Tutor - You've got a lot of tutors, you can cut this one.

Final Parting - Same as above.

Diabolic Tutor - You can guess what I've got to say about this one.

Platinum Angel - I think take this one out. You can't pay life below zero so I'm not sure why else this would be in the deck.

Phage the Untouchable - As you said, you'd put it in your maybeboard and have it come out a game or two so you can just say you've killed someone with Phage, but I'd probably just keep it in the maybeboard.

Orcish Bowmasters - What are you playing, CEDH?

Opposition AgentGC - This is really more a meta suggestion than anything, but you don't verse people with a lot of tutors, you'd be lucky if people run more than one tutor. I'd cut this just from a meta perspective, or at least have it as a maybeboard card.

Doomsday Excruciator - Eh, nah.

Dimir House Guard - It's a sac outlet and a tutor in one, so I see what you're going with, which is why I'm only partially suggesting it as a cut, but also it's not the best at either job.

Chainer, Dementia Master - Not sure I'm feeling Chainer in this deck specifically.

Bloodletter of Aclazotz - Would be a lovely card for our cube, but I think there are already better finishers in this deck.

Asmodeus the Archfiend - Another maybe cut. It's a fun and spicy card, but also you're losing a lot of life for an effect which you do better with other cards in here. You really don't want to have too many cards that do similar things, especially since you've got many tutors and draw cards.

Cabal Stronghold - You've got three basic lands. There is no world in which you could activate this card and get a payoff from it.

Emergence Zone - Playing stuff at instant speed doesn't really help your deck.

Rogue's Passage - Zero use in this deck.

/

I also have addition suggestions:

Torment of Hailfire - Not sure why this isn't here.

Swamp - Add one Swamp for every land cut.

Flarhoon13 on Atraxa's Dicebag of Holding (Need all the dice)

5 months ago

Nov 2 Atraxa's Dicebag of Holding lost to Rich's Zevlor, Elturel Exile. I had 28 counters on a Champion of Lambholt but two castings of Do or Die from Rich slowed me down enough for him to pull out Professor Onyx with the Chain of Smog for the win. I killed Matt on Sultai Gonti, Canny Acquisitor

Gidgetimer on Kess Combos

Dramatic Scepter combo (Dramatic Reversal + Isochron Scepter ) could be a wincon with the already present Professor Onyx, Guttersnipe, Kessig Flamebreather, Lambholt Raconteur  ^Flip, Ovika, Enigma Goliath, or Fiery Inscription.

Floop-The-Pig on Discard Mono Black

legendofa Thank you for your input, it is very much appreciated. I actually addded Chain of Smog ealier but didnt even think about making it an infinite combo with Professor Onyx. Ill add some of these other ones to the deck too

legendofa on Discard Mono Black

Welcome to the club, Floop-The-Pig!

My first thought here is Chain of Smog. On top of being another discard spell, you can repeatedly target yourself with Professor Onyx out to get a full life drain from all your opponents.

Doom Blade doesn't excite me, unless you know your opponents won't be running black. I've never used Temple of the False God, but it has kind of a reputation as a trap, that looks better than it is. Bojuka Bog is another graveyard exile effect that I recommend.

Also consider adding some more mass removal. Something like Black Sun's Zenith or Toxic Deluge would help clean up all the creatures that get through your discard effects.

DeinoStinkus on Rakdos I play your deck

Laughing Jasper Flint would excel in your gameplan, and Grim Initiate or Shambling Ghast would be good 1-drops.

Professor Onyx stands out as not being great for the gameplan, I highly recommend Tevesh Szat, Doom of Fools. Great sack outlet with great card draw, AND steals your opponent's commanders. In that same vein, Brainstealer Dragon.

Infernalshell on Inflicting Pain and Everlasting Bloodshed

Profet93 these are great suggestions, especially the lockout pieces in black since those are cards I'd never thought of using (or even really heard of before) and that'll protect my board pretty nicely. I also didn't realize there was a baby Cabal Coffers out there so that'll be an immediate include over Mortuary Mire or Grasping Dunes and Thespian's Stage will likely replace the other one since that'll give me access to better ramp.

The wincon(s) at this moment is either through combat damage or through sacrifice synergies with Syr Konrad, the Grim, Vein Ripper, and/or Zulaport Cutthroat and as a last resort Skithiryx, the Blight Dragon will help close out some games too. I toyed with the idea of Chain of Smog + Professor Onyx for an alternate wincon but that felt like it would be too close to cEDH for my pod since we generally don't play combos that are less than 3 cards.

ABunchofPigeons on Dihada Binder of Onyx?

1 year ago

Hey friends and degenerates - Trying to see if the Professor Onyx / Chain of Smog combo fits into a Dihada, Binder of Wills / Underworld Breach deck. Has anyone had experience brewing with this in that line? Thinking it might be good to have with Onakke Oathkeeper in the mix (get that in the grave to use it's ability to reanimate Professor Onyx if need be?)
