What do you think about Mission Briefing replacing Mnemonic Betrayal ? It synergises with Bolas's Citadel , dumping lands in the graveyard, and acts as a Snapcaster Mage .

Thanks for asking! You're all welcome to critique or ask any questions regarding this deck and I'll try to give some meaningful input.

Mnemonic Betrayal I feel like is more of a sideboard card that is incredibly powerful in the right meta. If it doesn't do much against decks you regularly play against feel free to drop it for the next most powerful card of your preference. It could be replaced by a cantrip, mana rock or a card draw engine like Sylvan Library if you continuously play against random opponents. You're right in that it's probably not worthy of being maindeck in this "stocklist". Otherwise you could use it as a flex splot for whatever card that works well in your meta like Verity Circle , Rhystic Study or Compost for instance.

Seat of the Synod is in the list to keep the singleton aspect of the manabase for Tainted Pact and enabling mox opal or niche Transmute Artifact synergies. If you play against cards like Null Rod a lot feel free to replace it with something that is more useful for you which could be for example Twilight Mire or Tarnished Citadel . Personally I don't like Tarnished Citadel due to heavy life loss which hurts your Bolas's Citadel and Ad Nauseam potential.

Me again, I am wondering about a couple of your card choices, mainly Mnemonic Betrayal and Seat of the Synod . I don’t understand what these cards do for the deck and would like to know the reasoning behind them.

Hi Quadsimotto, thanks for commenting.

From the top... Yes, if you can flicker Hostage Taker , it can be great fun. I did, however find the Siren's Ruse / Hostage Taker combo to be rather slow and dropped those cards from later versions of this deck. Artful Takedown promises a lot, but you often have less than 4 mana available when you want to play it. When it comes off, it works well. I haven't even looked at Mass Manipulation , with 6, 8, 10 cmc, it really scares me. Mnemonic Betrayal is a strong side-board card, but it really only becomes playable fairly late in the game. My latest incarnation of this deck is Aggro Thief

Really like sirens ruse and hostage taker here. That seems like all day value. How are you finding artful takedown in play? Mass Manipulation might be a fun one off in this(I realize the UUUU is a bit demanding) definitely fits the theme. Or even a mid to late game Mnemonic Betrayal

At any rate, pretty sweet dimir brew.

OK - I have a list of ideas to throw into the mix... After commenting earlier on your deck, something kept nagging in the back of my head. There was something about your deck that didn't quite make sense, but I couldn't put my finger on it. Yes, we all know that cards like Clear the Mind or Gaea's Blessing can devastate mill decks, but your deck is not a pure mill deck...

Here goes - As there is a lot of enchantment removal in the current meta, to get value from Psychic Corrosion you really need to swing in with a lot of card-draw once it is on the field and I don't see space to add in more card draw. A big worry is that you seem to have no early defense or negation, leaving you vulnerable to both control heavy and aggro decks. Swapping out Psychic Corrosion for Thoughtbound Phantasm might just swing the balance, creating a more resilient mid-range deck. Then, lastly, I would really want to simplify and streamline your deck, getting rid of the once-off cards that might work if you drew them at the right time. I have tried Mnemonic Betrayal in a few different decks and each time found that it promises far more than it delivers.

My version of this deck would be something like Steal or Discard, but that alternative probably still needs some work.

Hey Artatras,

thank you for your interesting, I'll write from now on the changes directly in the updates-window. If someone is reading this, I compare this deck with "The Many-Faced God" - [[Primer]]

Enhanced Surveillance performs in this deck very well, because I've put many cards with the Surveil-ability in it. The second ability of this card is also useful in an emergency case like any effect is going to exile all graveyard cards. If those cards go back into the library it isn't the worst, for sure better than getting away from the game. This card is no power-up, but I like it a lot and with many Surveil-cards this enchantment fits in this decks strategy. I don't see this card in your deck, you have a lot of cards to loot cards like Looter il-Kor , Key to the City ,.. and not so much Surveil-cards. In my opinion Enhanced Surveillance needs many Dimir cards with the named ability. This is just a fine difference between our decks, guess it's not worth to skip any other card for this specific one.

Yes, Telepathy is awesome, especially in this control-fancy playstyle. In commander we know that we can't counter everything (and that's for so many reasons really good!) so this helps a lot to get advantage in the game. I recommend this card a lot. It doesn't do anything on it's own, but not only you can see other players hand. Each opponent may get suspicious too when seeing any other opponents cards. I see this card in any deck which has a passive strategy.

In my deck there are of course many possible upgrades, but I'm not interested to rise up the power level to a 9 or 10 of 10. First it's hard to achieve, second those decks have a very strict game plan and last I like to play anything interesting like Thief of Sanity , Mnemonic Betrayal ,... Recently I changed some cards, hope it does work well. One card I try is Dark Confidant over Phyrexian Arena , because of a very low average CMC and the Confidant is in addtion a creature card too.

I'm monitoring your deck as well and I like it as a really good reference. To your question of which cards I'm considering at the moment: Perplexing Chimera , Dimir Doppelganger and Psychic Intrusion . I've put in Ashiok, Nightmare Weaver to force the deck theme in a specific direction.
