What it does
"Mine Vibranium" isn't a real Magic: The Gathering keyword or ability—it sounds like a mashup of Marvel terminology (Vibranium is the fictional metal from Black Panther) and a generic resource-gathering mechanic. While Marvel and Magic have crossed over in recent Universes Beyond sets, there's no established MTG ability by this name.
If you encountered this on a card, double-check the exact wording, as it may be a custom, fan-made, or proxy card rather than an official printing. Real MTG mechanics that "generate resources" include things like Treasure tokens (sacrifice for any color of mana), Clue tokens (pay mana and sacrifice to draw), or Powerstones (mana usable mostly for artifacts).
If you can share the card's actual rules text, I'll gladly explain how it functions and where it shines in Commander.
