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

3 weeks 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

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.

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

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.

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.

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?)

also, here are some more cards I found that might be helpful for the deck: Volrath's Laboratory, Vanquisher's Banner, Blood for Bones, Mastermind's Acquisition, Epic Downfall, Professor Onyx, Conspiracy, Doom Blade, Ghastly Demise, Nezumi Graverobber  ^Flip, and Crippling Fear
