Cavern of Souls is a rare land that offers significant advantages for creature-based decks. Its power level is high due to its ability to generate multiple mana and protect creatures from counterspells. When it enters the battlefield, you choose a creature type, and then it generates two types of mana: one colorless {T} mana and one additional mana of any color. This mana can only be used to cast a creature spell of the chosen type, making it an excellent enabler for combo decks.

In Commander, Cavern of Souls is a staple in many creature-based strategies. It pairs well with cards like Sylvan Caryatid, which generates card advantage and sets up the board for additional plays. When combined with a consistent mana source, Cavern of Souls can enable aggressive plays or provide a safe way to generate mana while protecting your creatures.

In Modern and other formats, Cavern of Souls is often used in more complex decks that rely on its ability to protect powerful creatures from counterspells.

Cavern of Souls: A Land with a Twist

Cavern of Souls is a rare land from the Avacyn Restored set. Its unique ability to grant a specific creature type when it enters the battlefield sets it apart from other lands.

Keyword Abilities and Rules Interactions

• As this land enters, choose a creature type: This ability triggers as Cavern of Souls enters the battlefield, allowing you to specify a creature type.
• {T}: Add {C}.: The first triggered ability allows you to add one mana of colorless, which can be used for any spell that requires colorless mana.
• {T}: Add one mana of any color. Spend this mana only to cast a creature spell of the chosen type, and that spell can't be countered.: The second triggered ability adds one mana of any color, but it has a specific restriction: you can only use this mana to cast a creature spell with the chosen type.

Function on the Stack and Battlefield

When Cavern of Souls enters the battlefield, choose a creature type. This choice is crucial, as it will determine what creatures you can cast using its second ability. For example, if you choose "Wizard" as your creature type, you can only use the mana generated by Cavern of Souls to cast a Wizard creature spell.

The first triggered ability allows you to add colorless mana, which can be used for any spell that requires it. However, the second ability is more restrictive, allowing you to add one mana of any color, but only if spent on a creature spell with the chosen type.

Edge Cases and Unusual Interactions

• If you choose "Creature" as your creature type (note: this is not an actual creature type), you can use the mana generated by Cavern of Souls to cast any creature spell. This may seem counterintuitive, but it's an important edge case to consider.
• If you cast a spell that has multiple creature types (e.g., a Beast Wizard), you can only use the mana from Cavern of Souls if the chosen type is one of the listed types.
• Cavern of Souls interacts well with other cards like Sylvan Caryatid or Eldrazi Conscription, which provide additional sources of colorless or specific-colored mana.

Commander-Specific Quirks

Cavern of Souls can be a valuable addition to Commander decks that rely on creatures, especially those with specific creature types. Its ability to grant a chosen type and generate additional mana makes it an attractive option for players who want to build around a particular archetype.

Cavern of Souls is a versatile and powerful land that has been a staple in many Commander decks, particularly those focused on Tribal strategies. Its ability to grant a chosen creature type an additional mana source and protection from counterspells makes it an attractive addition to any deck featuring creatures as its core.

One popular application of Cavern of Souls is in Merfolk Tribal decks, where players can choose the "Fish" type and gain access to a wealth of blue and multicolored merfolk creatures. Liliana's Mastery and Jace, Architect of Boats are common inclusions that benefit greatly from Cavern of Souls' ability.

Another strategy that benefits from Cavern of Souls is the Simic Shops archetype, which revolves around generating card advantage through artifacts and counterspells. Players can choose the "Artifact Creature" type and generate a significant amount of mana to fuel their token generation engines.

In addition, Cavern of Souls has seen play in more niche Commander strategies, such as the Gruul Animate strategy, where players use red creatures with animate effects to create an army of tokens. Choosing the "Goblin" or "Wolverine" type can grant access to powerful creatures like Keldon Marauders and Kemba, Kha Regent, respectively.

Its inclusion in casual Commander decks is also common, as it allows players to run more creature-heavy lists without sacrificing card advantage. The flexibility of Cavern of Souls makes it an excellent choice for decks focused on Tribal or token generation strategies.

In competitive metagames, Cavern of Souls has seen play in a few top-tier decks, including Nicol Bolas, Dragon-God and Atraxa, Praetors' Voice. Its ability to grant protection from counterspells and generate additional mana makes it an attractive inclusion for players looking to run high-powered creature spells.

Overall, Cavern of Souls is a highly versatile land that has been adopted by many Commander strategies due to its unique ability to provide both card advantage and protection from counterspells.

Cavern of Souls is a versatile land that offers an array of creative possibilities, particularly in Commander decks. By choosing a creature type as it enters the battlefield, players can set up for specific creature-based strategies.

• Merfolk tribal:

  • **Daxton**]: Equip a Merfolk with Daxton's shell, granting them an impressive +3/+2 boost.
  • Combine it with Merrow Reejerey and other Merfolk to swarm the board.

  • Insect tribal:

  • Pair Cavern of Souls with Mwonvuli Acid-Moss for a cheap way to produce black mana, which is essential for casting Insects like Golgari Findbroker.

  • Combine it with Giant Spider and other Insects for a powerful swarm strategy.

  • Witch tribal:

  • Sakashima the All-Seeing: Equip a Witch creature with Sakashima, giving them +4/+2 and lifelink.

In addition to these specific tribe strategies, Cavern of Souls can be used to create more complex interactions. For example, pairing it with Eternity Snare allows for a land-based "squirrel" effect: sacrifice the land to generate life and card advantage.

Furthermore, Cavern of Souls has seen play in various non-tribal Commander decks as a means to generate colorless mana, especially when combined with other lands like Command Tower.

Cavern of Souls is a versatile land that can greatly enhance creature-heavy Commander decks. However, players often make mistakes when playing this card, particularly regarding timing and misunderstood rules.

Timing Issues

• Waiting too long to choose a creature type: Players may assume they have more time to think about the optimal creature type or try to change their choice later. However, once Cavern of Souls enters the battlefield, you must choose a creature type immediately. If you're unsure, it's better to make an educated guess and adjust your plan accordingly.
• Not considering mana availability: When using the second ability to add one mana of any color, players often overlook the need for adequate mana development. Make sure you have a sufficient mana base and consider cards like Mox Opal or Simian Spirit Guide to accelerate your mana generation.

Misunderstood Rules

• Not realizing that spells can't be countered: Players may think they can counter a spell cast with the second ability, but this is not possible. Be cautious when casting spells that could be crucial for your game plan.
• Assuming all creatures can be cast with the second ability: The second ability only allows you to spend the added mana on a creature of the chosen type. If the creature doesn't have an available color, or if it's a multicolored creature and its additional colors aren't among those generated by Cavern of Souls, you won't be able to cast it.

Poor Synergies

• Not pairing with cards that benefit from accelerated mana: Players often overlook synergies between Cavern of Souls and cards like Eldrazi Disintegrator or Soul Wist. These creatures can greatly benefit from the additional mana generated by Cavern of Souls, making it essential to include them in your deck.
• Not including a broad range of creature types: Players may assume that choosing a popular creature type will suffice. However, having access to multiple creature types through Cavern of Souls allows you to adapt to changing circumstances and playstyle shifts.

By understanding these common mistakes, players can harness the full potential of Cavern of Souls in their Commander decks and make informed decisions about how to utilize its unique abilities.

Cavern of Souls is a versatile and powerful land that enables creature-heavy strategies. It's particularly well-suited for decks built around specific creature types, as it allows players to cast creatures without paying their mana cost.

Commander Pairings:

• Anafenza, the Foremost: A great pairing with Cavern of Souls, as Anafenza's ability to create 2/2 tokens that are a copy of any creature in play can be amplified by casting creature spells from Cavern.
• Azami, Lady of Scrolls: Azami's ability to add mana of any color can be used to cast creatures from Cavern, while also enabling the deck to run a more varied mix of colors.

Color Identities and Themes:

• Green-White: A classic combination for creature-heavy decks, Cavern of Souls pairs well with cards like Avacyn, Angel of Hope and Vinescale Healer. Green-White can also benefit from other lands that provide additional mana, such as Fountain of Renewal.
• Azorius White: A more aggressive take on the color combination, Azorius White can utilize Cavern's ability to cast low-cost creatures like Ajani's Pridemate and Serra Angel. Cards like Ajani Vengeant also provide a strong synergy with Cavern.

Synergy Cards:

• Banshee Blaster: This card provides a cheap way to sacrifice creatures to Cavern, generating additional mana for casting.
• Pharika's Blessing: By sacrificing two creatures, you can generate three mana, allowing for the casting of more expensive creatures from Cavern.

Combo Notes:

• Cavern + Anafenza: Cast a creature from Cavern using its second ability, then use Anafenza to create additional tokens that are copies of the same creature.
• Azami + Cavern: Use Azami's ability to add mana of any color, then cast a creature from Cavern. The added mana can be used for further spells or as part of larger combos.

Format Breakdown

Cavern of Souls is a format-defining land that sees play in various formats, but shines brightest in Commander.

• Commander: Cavern of Souls is an essential addition to any Commander deck. Its ability to add one mana of any color makes it an excellent fixer, allowing players to cast creatures without worrying about the land's type or color restriction. The added benefit of being able to spend the extra mana only on a creature spell of the chosen type, and that spell can't be countered, makes it a game-changer in this format.
• Modern: While Cavern of Souls is not as ubiquitous in Modern as in Commander, it still sees play in some decks. Its ability to add one mana of any color is beneficial in formats where mana fixing is crucial. However, its relatively high price point and limited utility outside of creature-heavy decks make it less competitive.
• Standard: Cavern of Souls has been banned in Standard due to its overpowered nature in combination with powerful creatures.

Competitive Considerations

In Commander, Cavern of Souls is a staple in many decks, particularly those focused on playing multiple colors. Its versatility and ability to fix mana make it an excellent choice for players looking to cast a wide range of creatures. However, its high price point may limit its inclusion in more budget-conscious decks.

Casual Play

Cavern of Souls remains a popular choice among casual players due to its ease of use and flexibility. Its ability to add one mana of any color makes it an excellent addition to beginner-friendly decks or those focused on creature-based strategies.

Banned in Standard

As mentioned earlier, Cavern of Souls has been banned in Standard due to its potential for abuse with powerful creatures. This is a testament to the card's impact and influence on gameplay.

Overlooked?

While Cavern of Souls may not be as widely played in formats outside of Commander, it remains an essential component of many creature-heavy decks. Its utility and flexibility make it a staple in many players' collections.

Cavern of Souls is a versatile land that excels in scenarios where you need to cast creatures with specific types. Here are some key matchups and strategies:

Mono-Color Aggro Decks: Cavern of Souls shines in these decks, allowing you to cast powerful creature spells like Goblin Guide or Monastery Mentor. By choosing a specific creature type, you can add one mana of any color to play your creatures on the turn they enter.

Creature Type Diversified Decks: In decks with a diverse creature pool, Cavern of Souls enables you to play multiple creatures from the same type without worrying about running out of colors. For example, if you have Wulfgar, Daxos of Meletis, and other creature spells that share the Human or Elf type, Cavern of Souls allows you to choose that type and add one mana of any color.

Anti-Combo Decks: In anti-combo decks focused on disrupting opponents' plans, Cavern of Souls can be used to play Doom Blade or Path to Exile by choosing the Artifact type. This way, you can remove artifacts and planeswalkers that might be part of an opponent's combo.

Multiplayer Politics: In multiplayer games, Cavern of Souls can be a game-changer when playing against opponents with powerful creatures. By choosing a specific creature type, you can add one mana to play a counterspell or removal spell, disrupting your opponents' plans and gaining an advantage.

In matchups where opponents have access to Mana Leak or Countersquall, Cavern of Souls's ability to prevent countered spells is less valuable. Additionally, in decks with low creature density or without multiple creatures from the same type, Cavern of Souls may not be as impactful.

Cavern of Souls has a storied history in Magic: The Gathering. It was first introduced in the Archenemy set, released in 2010, and has since become a staple in many decks. One notable aspect is its versatility, allowing players to choose a creature type as it enters the battlefield.

Its mana-producing abilities grant two colorless mana or one additional mana of any color on demand, with specific restrictions for casting creature spells of the chosen type. This unique synergy can prove powerful when combined with cards like [Soul Wist". In recent years, Cavern of Souls has seen significant play in various formats, including Modern and Legacy.

EDHREC rankings have consistently placed it within the top 200 most-played lands, indicating its popularity among casual players. However, prices have fluctuated over time; currently, a copy costs around $38.62 USD or $34.22 EUR, while the foil version is priced at $79.98 USD.

Tournament presence has been notable, particularly in events featuring combo-heavy decks that capitalize on Cavern of Souls' benefits. Its combination with Elder Island and Omniscience exemplifies this synergy, creating an incredibly formidable team of creatures. The card's widespread adoption is a testament to its impact on Magic's competitive scene.

In terms of iconic decks, Cavern of Souls has been featured prominently in various 'Combo' archetypes, leveraging its unique abilities to generate mana and evade counterspells. Its inclusion often necessitates specific creature-based sideboarding strategies to maximize its potential. While not as ubiquitous as Misty Rainforest or Polluted Delta, Cavern of Souls holds an esteemed position within Magic's history.

Cavern of Souls is a mystical land that taps into the raw energy of the multiverse, granting its wielder unparalleled access to powerful creatures. This rare artifact is said to be hidden deep within ancient caverns, where the whispers of the past still linger in the air.

When Cavern of Souls enters play, its controller must choose a creature type - whether it's a majestic dragon, a cunning thief, or a mighty warrior. Once this choice is made, the land begins to radiate energy that can be channeled into casting spells.

The first ability allows the player to add one mana of any color to their pool. This mana can be used for any number of spells, but it's especially potent when paired with Llanowar Elves or other mana acceleration cards. However, the second ability is where Cavern of Souls truly shines - allowing its controller to spend this additional mana only on creature spells that match the chosen type.

This twist on traditional land play adds a layer of strategy and unpredictability to games featuring Cavern of Souls. Players must carefully consider which creatures they'll want to cast, weighing the benefits of playing around removal spells or leveraging their opponent's own creature types against them.

The legendary planeswalker Jace, the Mind Sculptor often speaks about the delicate balance between creation and destruction in the multiverse, and Cavern of Souls embodies this concept. By granting access to powerful creatures while also limiting its use to a specific type, the land challenges players to think creatively about their deck's composition and playstyle.

In some corners of the multiverse, Cavern of Souls is said to be connected to an ancient network of dimensional pockets, where long-forgotten civilizations once thrived. These whispers speak of a time when the land was a nexus for interdimensional travel, allowing beings from across the cosmos to share knowledge and power.

As a result, Cavern of Souls has become a prized artifact among those seeking to harness its raw energy and unlock new possibilities in their quest for mastery over the multiverse.
