Some terms have an unofficial but widely known meaning in Magic jargon. For example, a "cantrip" is a spell that lets you draw a card, and a "bear" is a vanilla 2/2 (with "vanilla" having its own meaning!)

What about a card that produces mana like Sol Ring, Rakdos Signet, or Talisman of Indulgence? Do they have an unofficial name?


The canonical name for these seems to be 'Mana Rocks', probably so named after one of the very first, Fellwar Stone.

  • The number of Google results is impressive. This does indeed appear to be an accepted term. – ikegami Nov 29 '12 at 9:58
  • Does a Mox count as a "Mana Rock"? How about a Black Lotus? Surely not! – thesunneversets Nov 29 '12 at 10:58
  • I'm pretty sure the name refers to the Moxes, not Fellwar Stone. – bwarner Nov 29 '12 at 14:13
  • I'm less sure it refers to the Moxes (though not entirely sure it refers to Fellwar Stone either); the term seems to have primarily originated in EDH/Commander play, where moxen are outright banned. It's more likely than anything else, I suppose, to be an offshoot of 'brown' as the color of artifacts and the notion of artifacts as generically being mineral of some sort or another. – Steven Stadnicki Nov 29 '12 at 20:37
  • "Mox" is typically a term to itself meaning a 0-cost artifact that produces mana. – WLPhoenix Dec 6 '12 at 20:57

"Mana Rocks" might be a genuine term, but I don't think it's a particularly useful one, as it's not very descriptive of the use of these cards.

If I was talking about this class of card, in a way more likely to explain why I'd want to include some in my decks, I'd just go for "artifact-based mana acceleration". I know this answers your question less well than Steven's answer, but on the other hand I, and I'm sure many others, would never use the term "mana rocks"!
