All 12 Green Mana Rocks in Magic Ranked

Green is Magic’s premier ramp color, but it doesn't like artifacts that much; it usually prefers mana dorks and cheating extra lands into play.

Still, green mana rocks do exist… and a couple of them are among MTG's most powerful artifacts ever printed.

Let’s get into them!

What Are Green Mana Rocks in MTG?

In MTG slang, a “mana rock” is an artifact that can produce mana. For this ranking, we’re narrowing it to green mana rocks, so artifacts with a mono-green color identity that tap to produce mana.

That means something like Moss Diamond, which taps for green mana, fits our definition. But an artifact like Arcane Signet doesn’t: Even though it can tap for green in a mono-green Commander deck, it doesn't have a mono-green color identity. That doesn't mean you can't fit Arcane Signet into a mono-green deck, but color identity matters for our purposes.

We'll also exclude artifact lands (like Tree of Tales) and artifact creatures (like Copper Myr), and focus strictly on artifacts, since that's what's usually understood by “mana rocks” (creatures are a lot easier to kill than “just-artifacts”, and playing Tree of Tales counts as having played a land that turn).

Honorable Mention: Eumidian Lifeseed

This Alchemy-only card cantrips into one of a number of different utility lands, including all the planets from Edge of Eternities. Providing mana for the lands you pick up is a nice bonus, though you'll want some artifact synergies or land payoffs before you slot this into your next MTG Arena deck.

#12. Green Mana Battery

Alright, let's not mince words here: Green Mana Battery is what a bad card looks like. A really bad card, even! But since every ranking needs a worst card, that's an easy place to place this thing.

#11. Weatherseed Totem

Weatherseed Totem is a 3-mana rock that taps for green, with the option to spend 5 mana to turn it into a 5/3 treefolk artifact creature with trample for the turn. And it has the cute triggered ability that, if it goes to the graveyard while it’s a creature, returns it to your hand.

So, yeah, still a pretty awful mana rock. But it does do some cool things!

#10. Horn of Ramos

Horn of Ramos is part of a cycle from Mercadian Masques, and it’s another mediocre 3-mana rock with a cute trick attached… although in this case the trick is at least starting to look useful. You can sac it even if tapped for a short burst of when needed.

Most decks still don’t want to pay 3 mana for a rock that normally only produces , but decks interested in artifact sacrifice on demand, recursion, or generating one big burst of mana can squeeze some extra value out of it.

Nothing spectacular, but at least Horn of Ramos has a plan!

#9. Veloheart Bike

I suppose if you're trying to do some sort of lower-Bracket vehicle thing you might get away with Veloheart Bike, but you need some pretty strong vehicle synergies to justify this. A mana rock that can trade off for a creature later isn't exactly nothing, but it's not a compelling enough reason to choose this over other 3-cost mana rocks, colorless or otherwise.

#8. Necklace of Girion

Okay, now we're getting somewhere.

Necklace of Girion, from The Hobbit Commander, costs 3 mana and taps for green, but it also puts a +1/+1 counter on a creature whenever you cast a green spell and whenever a forest you control enters. In the right deck, that can turn an otherwise inefficient mana rock into a steady counter engine. And notice it's when you cast any green spell; it doesn't have to be a spell that you used Necklace of Girion‘s mana to cast.

It’s especially appealing in +1/+1 counter decks, where you were already interested in repeatedly triggering counter synergies. And forest-heavy landfall decks can also trigger it naturally just by doing what green does best.

#7. Moss Diamond

Nothing fancy here: Moss Diamond costs 2, enters tapped, and taps for green. That’s the whole card.

It's generally worse than Arcane Signet, even in mono-green (entering tapped is a pretty big drawback), and green is arguably the color least desperate for mediocre mana rocks… but still, Moss Diamond is a boring but serviceable option.

#6. Kolvori, God of Kinship / The Ringhart Crest

We’re really ranking The Ringhart Crest here, of course, which is the artifact face of Kolvori, God of Kinship, but the flexibility of having another face (when a mana rock isn’t what you need) sure is part of what makes this MDFC a pretty good green rock.

The Ringhart Crest does have a fairly strict restriction (it only works with either the creature type you've chosen or legendary creatures), but it’s barely a drawback in the decks built to exploit it. Two mana and entering untapped puts it in line with Arcane Signet. And if you draw it when ramp isn't what you need, you can simply cast Kolvori, God of Kinship instead.

#5. Jade Orb of Dragonkind

Three-mana rocks need a pretty good excuse to be in your deck (and to make you happy about it), but Jade Orb of Dragonkind has one.

It taps for a single green mana, but when you cast a dragon with that mana it enters with a +1/+1 counter and hexproof until your next turn. And, unlike The Ringhart Crest, you can use Jade Orb of Dragonkind‘s mana for anything you want, so you’re free to spend it elsewhere when needed.

Obviously, that makes Jade Orb of Dragonkind a better fit for dragon decks (which tend to be multi- or 5-color) than strictly mono-green decks. But if you’re playing dragons and leaning green, this is a pretty good green mana rock.

#4. Herd Heirloom

We don't have the green Infinity Stone yet, but Herd Heirloom feels like a fine, totally destructible place-holder. It offers trample and card draw for green decks with large creatures, which is quite the alternative mode to a mana ability that already fixes all colors for creatures. That's a pretty big upgrade over Mind Stone!

#3. Ancient Cornucopia

It's really easy to write off Ancient Cornucopia as a sort of color-restricted Pristine Talisman, but it's so much better than that. Multicolor decks need access to all colors, and they need to buy time to get to their huge payoffs. Cornucopia covers both ends by fixing for all colors while also gaining chunks of life. It's very easy to be up 5-10 life over a few turns while also progressing your gameplan.

#2. The Great Henge

With a massive jump in card quality… here comes The Great Henge!

For starters, it never costs 9 mana in any self-respecting green deck: Its cost drops according to the greatest power among creatures you control, and creature-heavy green decks can routinely knock a huge chunk off that price.

Once it resolves, the Henge taps for 2 green mana while gaining you life. And every nontoken creature you play afterward enters with a +1/+1 counter and draws you a card. And that's nontoken creatures you put into play, not just those that you cast; if you blink or resurrect a creature, it gets a counter, too!

That combination of ramp, card advantage, lifegain, and counters makes The Great Henge one of the very best green cards for Commander (and it also happens to be an excellent green mana rock).

#1. Mox Emerald

Remember Green Mana Battery? The poster child of a bad card?

Well, here's the complete opposite: one of Magic’s infamous Power Nine cards. Mox Emerald costs 0 mana and taps for green. No setup. No entering tapped. No 3-mana investment followed by an upside that desperately tries to justify the 3-mana investment. Just in, out.

It's so powerful that most Magic players have never seen this card in play… because it's only allowed in Vintage, MTG's most powerful (and expensive!) format.

But, yeah, this is the best of the best. Turns out free mana is pretty good. Who knew?

Green Cards That Create Mana Rocks

Besides cards that are mana rocks themselves, there are a handful of green cards that create mana-producing artifact tokens.

Tireless Provisioner is probably the cleanest example. Every land that enters under your control can create a Treasure (or a Food token), which turns green’s excellent land-ramp package into even more mana.

Aggressive decks could go for Old Gnawbone, who creates Treasure tokens equal to the combat damage your creatures deal to players. One good combat step can leave you with a rather absurd pile of disposable mana rocks.

And Treasures aren’t the only option. Cards like Argothian Opportunist creates a tapped Powerstone when they enter, giving you a reusable artifact mana source, although you can’t spend that mana to cast nonartifact spells.

None of these qualify as green mana rocks according to our definition (these cards themselves aren’t mana rocks, and the tokens they create don’t exclusively produce green mana), but if what you actually want is artifact-based ramp in your green deck, you certainly have these options.

Green’s short list of mana rocks is a bit of an odd bunch, but it does include two of the strongest artifacts ever printed.

But what do you think? Are any of these green rocks criminally underrated? Do you still have a soft spot for Moss Diamond? Let us know in the comments below or over on the Draftsim Discord. For more from us, check out our YouTube channel, The Daily Upkeep.
