That's actually pretty cool that your group does that, for Grixis colors and Bolas in a 7 player pod. I would think that a Cruel control kind of theme would work great, having a lot of worldly effect and ramp hard enough to cast your spells.

I would recommend adding in all the low costed and effiecient 1-3 drop mana rocks. As well as some fun cards like Diluvian Primordial or Sepulchral Primordial. Some new cards that can be fun with a lot of mana are cards like Mnemonic Betrayal. Also some more of the protection package so you can make it to the late game would be great, some cards to be considered are like Evacuation or Cyclonic Rift.

Waste Not can be good if you plan to use cards like Windfall, Whispering Madness, or Reforge the Soul. Wheel of Fortune as well but that's a tad too expensive. Kess, Dissident Mage can also be good value in reusing all the cards you pitched away.

Hope that helps and let me know if ya wanna brainstorm more!

You might want to have a look at Ghoulcaller's Bell, Codex Shredder, Pyxis of Pandemonium, Lantern of Insight, Isochron Scepter and Dramatic Reversal. Also Mnemonic Betrayal (Yawgmoth's Will for your opponents' cards) is really good when you mill. I would reconsider the mana rocks you have, especially since you are missing the cheap (money-wise) but good ones such as Fellwar Stone, Talisman of Dominance, Dimir Signet. Dark Ritual is a must play.

Notion thief will want Windfall, Timetwister, Whispering Madness, Time Spiral...whatever your budget allows.

yeah i was wondering why Necropotence was in here as well also theirs some new dimir cards you can use as well like Fraying Sanity, Psychic Corrosion, Drowned Secrets, Thief of Sanity, Mnemonic Betrayal these would really boost your mill possibility

I def have, but this deck is more focused on exile rather than the graveyard, so unfortunately it didn't make the cut. I do have another deck I'm testing with Mnemonic Betrayal so i will post once i feel it's worthy.

Have you considered Mnemonic Betrayal so you can steal the cards you make them discard as well, and as a counter to the newer Surveil/Jump-Start/Undergrowth mechanics?

Thank you for the input!! It is much appreciated.

Commander's Sphere: I 100% agree with replacing Obelisk of Grixis and will make that change immediately.

Mnemonic Betrayal: will definitely be included once I am able to obtain one. I was thrilled when this card spoiled from GRN and all of the fun possibilities it has!

Cloudstone Curio: though I am looking for maybe one more blink effect I don’t think this is it. This card allows me to return it to my hand, but I most definitely don’t want that with some of the bigger threats I am casting, and if I am casting them for the unearth cost, returning them to my hand would cause them to exile. If I had more ETB triggers this would be a great card for my deck.

Again, thank you for the input!

I think the original Lazav is better than the new one. Casting cost may dissuade you tho which is understandable.

Commander's Sphere is just a better Obelisk of Grixis.

Mnemonic Betrayal is so good, definitely deserves an include.

Cloudstone Curio is another good flicker option if you find yourself needing another.

randomguyguy You beat Teferi with a single copy of Unmoored Ego or Vraska's Contempt. I don't think this discard is weak against control, not with Duress in the sideboard. I can tell you that in some ways Grixis is weaker than a Jeskai deck until you go to the board, but not all. At which point you board in your threat management. Blood Operative is bad. Again, you'll just Unmoored Ego the Experimental Frenzy or out right counter it, or force it to be discarded with Duress in a sideboard. You have to know the meta to handle it. I look at the combo with Fight with Fire and Expansion / Explosion as icing, not the real deal closer. Boarding that combo out is entirely possible if playing into counters. As far as graveyard hate, I do agree its a bit light in that regard, and maybe a Sentinel Totem in the board is handy. I am open to Mnemonic Betrayal as well. I think that could be right on the money, but so many will argue its a horrible card. I don't think it is...but at the same time the right match up could make this amazing. How to be resolved Experimental Frenzy is Dream Eater or River's Rebuke into Duress / Unmoored Ego / Sinister Sabotage / Disinformation Campaign. Costly in all regards. Thank you for the input though. I'm gonna take your suggestions up though.
