Text of card

Exile all cards from all opponents' graveyards. You may cast those cards this turn, and you may spend mana as though it were mana of any type to cast those spells. At the beginning of the next end step, if any of those cards remain exiled, return them to their owners' graveyards. Exile Mnemonic Betrayal.


Card Pros

Card Advantage: Mnemonic Betrayal gives you access to every opponent’s graveyard, potentially flooding your hand with options and overwhelming opponents with their own spells.

Resource Acceleration: By utilizing the spells of your adversaries, this card can effectively accelerate your resources as you cast spells without expending your own cards, preserving them for critical moments.

Instant Speed: While Mnemonic Betrayal is a sorcery, its ability to tap into a vast array of instant-speed spells within graveyards offers a strategic flexibility usually reserved for actual instant spells.


Card Cons

Discard Requirement: Mnemonic Betrayal mandates an exile of itself until the end of turn as part of its resolution. This can stifle recurring usage strategies and limits the potential for exploiting its powerful effect within the same turn or in consecutive turns.

Specific Mana Cost: With a specific mana requirement of one blue, one black, and one colorless, this card demands a heavy commitment in a deck to two colors. This can be restrictive for players not running a dedicated Dimir setup or who lack the necessary mana fixing to consistently cast it on curve.

Comparatively High Mana Cost: With a casting cost totaling three mana and the additional setup to make it effective, Mnemonic Betrayal’s mana investment might be too steep compared to other cards in the same mana range. In environments where efficiency is key, its impact may not justify its cost, especially if the opposing graveyard lacks high-value targets at the time of casting.


Reasons to Include Mnemonic Betrayal in Your Collection

Versatility: Mnemonic Betrayal can adapt to a variety of strategies. This card temporarily exiles an opponent’s graveyard and lets you play those cards, which means its utility varies depending on what your opponent has in their graveyard.

Combo Potential: This card has significant synergy with setups that benefit from casting numerous spells in a single turn or that capitalize on opponents’ strategies and cards.

Meta-Relevance: With graveyard strategies frequently appearing in various formats, having Mnemonic Betrayal in your collection provides a tactical edge, allowing you to turn the tables using the tools from your opponent’s own game plan.


How to beat

Mnemonic Betrayal is a unique card in the MTG multiverse that requires thoughtful strategy to counteract. This card allows a player to cast spells from their opponent’s graveyard for a turn, potentially turning the tides of the game. When playing against an opponent wielding Mnemonic Betrayal, it’s critical to manage your own graveyard carefully. Having cards with graveyard shuffling capabilities like Elixir of Immortality can prevent crucial spells from being snatched away. Additionally, instant-speed removal such as Tormod’s Crypt can exile your graveyard in response, rendering Mnemonic Betrayal ineffective.

It’s also advisable to keep an eye on your opponent’s mana. Given that Mnemonic Betrayal is a higher-cost spell, it often requires a turn of setup. Being proactive with disruption tools like Thoughtseize or counterspells, which target the stack, can stop the spell altogether before it takes effect. It’s clear that while Mnemonic Betrayal can be powerful, with the right countermeasures and a proactive stance, one can maintain control over their own spells and diminish the impact of this potentially devastating card.

Every card in MTG has a counter, and Mnemonic Betrayal is no exception. With these strategies and a calm mindset, retaining the upper hand is an achievable feat.

Cards like Mnemonic Betrayal

Mnemonic Betrayal stands out in Magic: The Gathering as a unique sorcery that delves into opponents’ graveyards. When considering equivalents, Yawgmoth’s Will immediately comes to mind. It too permits playing cards from the graveyard, but it’s restricted solely to your graveyard and doesn’t exile those cards. Mnemonic Betrayal, by contrast, temporarily grants access to all opponents’ graveyards, yet it exiles itself and the played cards afterwards.

Another card worthy of comparison is Diluvian Primordial. Much like Mnemonic Betrayal, this creature allows you to cast spells from opponents’ graveyards when it enters the battlefield. However, it’s a one-time effect tied to a creature, whereas Mnemonic Betrayal is a sorcery which could be recurred from your own graveyard for repeated uses under the right circumstances. Lastly, there’s Gonti, Lord of Luxury, which also lets you play with an opponent’s cards. Though Gonti targets only the top four cards of an opponent’s library once it enters the battlefield, it shares the theme of using an opponent’s resources against them, a trait that’s at the heart of Mnemonic Betrayal’s design.

Exploring these comparisons, Mnemonic Betrayal adds a layer of versatility and deception, offering MTG players a potentially game-swerving play that draws from the collective past plays of opponents, solidifying its place in the pantheon of cards that twist the norms of gameplay.
