Why is this card good?
Charcoal Diamond is a serviceable but unspectacular mono-black ramp rock. It's a two-mana mana artifact that fixes nothing (it only makes black) and enters tapped, which means it doesn't accelerate you the turn you play it — a real tempo cost in a format that rewards explosive starts.
Where it earns a slot: mono-black decks that genuinely need more two-mana ramp to fuel commanders or big payoffs. Think reanimator shells, devotion/value piles, or any heavy-black deck wanting to hit a four- or five-drop on turn three. The diamonds also count toward devotion (a small bonus for Gray Merchant decks).
When NOT to play it: if your deck can run a colored rock that ramps untapped, you almost always should. Mind Stone, Charcoal Diamond's untapped cousins, and especially Arcane Signet or Mana Crypt outclass it. In two-color or more decks, signets and Talismans are strictly better fixing.
Bottom line: a filler ramp piece for budget or mono-black builds short on better options.
