Essential Spellbook - Mana Rocks

Rocks to Knock Your Socks Off

Let's pick up where we left off. The previous episode of Essential Spellbook presented a veritable salad bar of green cards. These cards provided ramp: access to additional mana beyond the mana available from playing one land per turn. Ramp is an essential element of almost every successful Commander deck because it allows you to cast expensive spells and make big plays earlier than your opponents.

However, once we look beyond green cards, options for ramp become more scarce. True, every color has access to cards that ramp, but these ramp effects are usually conditional (like Knight of the White Orchid

), temporary (like Seething Song
), or narrow in application (like Etherium Sculptor
). 

Because of this, many nongreen decks (and some green decks, too) rely on colorless cards to provide consistent, reliable mana acceleration, and by far the most common type of colorless ramp card is the humble mana rock.

What's a "Mana Rock?"

"Mana rock" is the colloquial term for any artifact that taps to produce mana. These cards provide a ramp solution that's appropriate for nearly any Commander deck. Some of these cards, like Sol Ring

and Arcane Signet
, are the closest thing in the Commander format to staples that go in every single deck.

In comparison to other forms of ramp, mana rocks are often very efficient. Unlike the previous article's land-based ramp and mana dorks, mana rocks can usually tap for mana the turn they're played. They're also available in a range of versatile flavors, sometimes tapping for multiple colors of mana

or providing useful benefits
 beyond ramp.

However, the efficiency and versatility of the humble mana rock is balanced by its relative fragility. In terms of vulnerability to removal, mana rocks fall somewhere between land-based ramp and mana dorks. They're not as fragile as creature-based ramp, like Elvish Mystic

, but they're definitely not as resilient as the extra lands generated by cards, like Rampant Growth
. It's not uncommon for a battlefield to be entirely cleared of artifact-based ramp mid-game by an effect like Vandalblast
 or Farewell
. Because of this, decks that rely on these cards for their ramp should consider including ways to protect their investment, like Teferi's Protection
, Counterspell
, or Heroic Intervention
.

Just as in the previous episode of Essential Spellbook, we're going to examine a representative card at each mana value and explore how it relates to other options at that mana value. Here we go!

Mana Value 1 or Less: Sol Ring

Love it or hate it, there's no more iconic card in Commander than Sol Ring

. This card has powered explosive games since even before Wizards of the Coast decided to print it in every single preconstructed Commander deck. If not for its reputation as the quintessential symbol of Commander, it would probably be banned from the format. It's just that strong.

Sol Ring

establishes a pretty clear baseline for evaluating mana rocks that cost 1 mana or less: they're almost all incredibly powerful. Some of the trinkets in this hall of fame include:

  • Mana Crypt
     is just Sol Ring
     but slightly cheaper and slightly riskier. Not in a way that matters, though: you'll win before the damage kills you.
  • Mana Vault
     provides a burst of mana, but then you need to pay mana to untap it. This card is a bit more niche than other options, but it's still very strong.
  • Chrome Mox
     and Mox Diamond
     cost no mana, but they demand that you give up a card in your hand. They're incredibly strong cards and staples of the high-powered corners of the Commander format.
  • Mox Opal
     and Mox Amber
     require a bit more setup before they provide mana, but the payoff is often worth the effort. Free mana is good, y'all.

(Okay, I lied. Not every mana rock that costs 1 mana or less is powerful. Springleaf Drum

is just okay, and Mox Tantalite
 leaves a lot to be desired. All the most-played cards in this category are incredibly powerful, though.)

When deciding whether to play these game-changing cards in your deck, you don't need to worry much about whether they're the right fit. Cards like Mana Crypt

and Mox Diamond
 will always make a deck stronger. Rather, before you add these to a deck, consider the type of games you want to be playing. These cards are often not appropriate for casual games of Commander because they represent a sheer level of power that most decks can't match. At best, they'll give your deck such an advantage over competitors that your opponents will band together to keep you in check. At worst, they'll trigger an arms race, incentivizing your opponents to trick out their decks with equally powerful cards in hopes of keeping up. Either way, you'll end up playing a very different game than you thought.

The exception, by group consensus, is Sol Ring

. No one bats an eye at Sol Ring
, because that's just the way Commander has always been. The card can still lead to unbalanced games, though, so some players choose to leave it on the sidelines.

Also, all of these cards are stupidly expensive, money-wise. Except for Sol Ring

, which is again the exception.

Mana Value 2: Signets and Talismans

Mana rocks that cost two mana are defined by two broad sets of cards: the Signets (such as Azorius Signet

and Simic Signet
) and the Talismans (such as Talisman of Progress
 and Talisman of Curiosity
). Also included here is Arcane Signet
, the format's second-most-played card, after Sol Ring
.

All of these cards tap for one mana (or one net mana, in the case of the Signets) while also providing access to multiple colors of mana. These little guys are the archetypal mana rocks: efficient, flexible, and suitable for almost every Commander deck.

Commander incorporates many, many other mana rocks with mana value 2, most of which trade some flexibility or efficiency for additional effects:

Like other ramp with mana value 2, these cards are especially valuable in decks with Commanders that cost 4 mana because they enable you to cast those spells on turn 3.

Mana Value 3: Commander's Sphere

Commander's Sphere

demonstrates that mana rocks with mana value 3 tend to tap for any color while offering an additional benefit, in Sphere
's case the ability to sacrifice itself for a card when extra mana isn't relevant.

Some mana rocks in this category worth considering include:

There are way more cards in this category than I can reasonably list in this article, but you can look through all of them here.

These cards often feel inefficient in comparison to rocks with mana value two, but sometimes the additional effects they offer are enough to compensate for their inflated cost. They're worth consideration in decks that care more about synergy than efficiency.

Mana Value 4 and beyond: Thran Dynamo

Once you're paying 4 or more mana for a mana rock, you'd better be getting something pretty great out of the deal. Like my representative pick, Thran Dynamo

, rocks at high mana values tend to produce a lot of mana. 

Like mana rocks at mana value 3, these cards are too diverse to list in full, but here are some highlights:

These rocks rarely see play except in decks that are truly gluttonous for mana, but they're a very good option if your game plan is to quickly reach double digits of mana (and you're not playing green).

Should I Play Mana Rocks?

As previously mentioned, mana rocks are an excellent way to ramp that's appropriate for almost every Commander deck. Some decks, however, are more likely to play mana rocks than others:

In contrast, certain considerations can incentivize a deckbuilder to choose other ramp cards instead of mana rocks:

  • If your deck includes green cards, you may have access to ramp cards that are more resilient
     or more efficient
     than mana rocks.
  • If your deck's strategy synergizes with another category of ramp cards, like treasure-producers
     or cost-reducers
    , those cards may compete for the same space in your deck as mana rocks.
  • If your deck (or your playgroup) incorporates many cards with the potential to wipe artifacts from the board, like Vandalblast
     or Cleansing Nova
    , mana rocks can be a liability in comparison to land-based ramp.

When it comes to choosing whether your deck wants rocks at mana value 2, mana value 3, or higher, many of the principles listed at the end of the previous episode of Essential Spellbook apply.

Putting the Rocks Back in the Box

Thank you for taking a tour of my rock collection. I hope you enjoyed the shine and sparkle. 

Do you have a favorite mana rock that I neglected to mention like the fool that I am? Let me know!
