Mnemonic Betrayal Discussion

Natux on The Inevitable Storm

Hey, sorry for the late response! I don't check TappedOut that often and was generally busy.

Just a very short explanation of some cards I'd cut:

Mox Amber Practically only good if you play your commander.

City of Solitude There's a bit too many of this same effect, you don't always need it.

Mass Hysteria Giving your opponent's creatures haste is a bigger downside than you'd expect.

Wheel of Fate Usually not needed during cascade turns, really bad outside of it.

Exploration Not a bad card, but not the best with just 28 lands.

Cephalid Coliseum Paying one life every time is a high cost, that's a few less cards with ad naus.

Red rituals in general. These are usually just relevant for casting generic costing spells. Blue/black is way more important.

You could also do with a little less artifacts, you get completely blown out by artifact hate.

Cards I'd consider:

Ad Nauseam It's in your maybe board and you should 100% play it. It's the best card in combo/storm decks.

Mystic Remora Also one of the best cEDH cards generally.

Carpet of Flowers If people you usually play with play blue (likely) then this card is a better, recurring dark ritual.

Bonus Round A wincon on it's own, especially with cards that untap such as frantic search and...

Snap Good removal that's usually free but gains mana with bonus round or cards such as...

High Tide This is incredibly good, but if you're going this route you should probably consider adding a few more islands.

Dark Petition A second copy of demonic tutor which becomes mana positive with bonus round.

Baral, Chief of Compliance Good with your creature synergies and is a cost reduction.

Mnemonic Betrayal Kind of meta dependant, take this with a grain of salt but I'd suggest you'd at least test it a few times.

Future Sight It's a combo with helm of awakening and sensei's top. I personally don't like this combo, but you still play helm.

For the rest you should just test what works for you and what works in your meta. Hopefully this helps some, feel free to send me a message again, I'll try to respond more quickly this time ;).

Making some small updates for RNA:

IN: Kaya, Orzhov Usurper , Mnemonic Betrayal , Hallowed Fountain , Forbidding Spirit

OUT: Teferi, Hero of Dominaria , Vedalken Plotter , Azorius Chancery , Juxtapose

Kaya and Betrayal is a new combo I want to try out (h/t Justin Parnell and Think Twice), so out goes valuable but off-theme Teferi and sometimes-useful Plotter. Hallowed Fountain is a strict upgrade, and Juxtapose felt clunky to me - so I'm trying out the Spirit. Any thoughts on these changes?

WKM on Esper Mill Control

Why Golden Demise instead of Cry of the Carnarium ? With all the board wipes you might not need it but Consecrate / Consume seems like a good fit Consume is a way to get around hexproof/indestructible and the lifegain can buy you time while Consecrate is a cantripping exile effect. I've worked with a similar premise though focusing more on mill and less on exiling and I've found Mnemonic Betrayal to be an interesting addition. Normally just allowing you to play there best cards but it also exiles there entire graveyard when it comes time to ultimate Kaya.

Natalbee on RNA Esper Control Attempt #1.5 - more exile

I would replace Sinister Sabotage with Thought Collapse . And if you wanna go a little more mill-y, you could add something like Psychic Corrosion or Patient Rebuilding . In fact, you could probably do some kind of Esper mill/control deck with Kaya, Orzhov Usurper and Mnemonic Betrayal / Sentinel Totem as an OTK...

Here's some more exile effects:

Unmoored Ego
Etrata, the Silencer
Cry of the Carnarium
Induced Amnesia

I wonder why still people play Phyrexian Arena There are so many better options in those colors. I added Mnemonic Betrayal instead. Does more and it's really fun to play.

And what do you think of a Mnemonic Betrayal package in your meta? Cards like Seeds of Innocence, Rampage of the Clans, Pernicious Deed lets you chain together your opponent's positive mana resources.

nerva90 on The Price of Blood

Yeah I feel you on Dawn of Hope, it's just a little too expensive it seems. I'll definitely be giving the partners a go. I'm also excited for Bloodchief Ascension. I'm using it as a win con in my Lazav deck right now where it combos mainly with Mindcrank but is also hilariously synergistic with Mnemonic Betrayal which basically just wins you the game most of the time. I'd probably put it in instead of Kambal, Consul of Allocation.

Thanks, I'll make sure to check them out!
