Mold Demon is a 6/6 trampler for six mana that lands with a serious condition attached: each opponent loses life equal to the number of Swamps you control, but you also lose life equal to the Forests they control. The symmetrical downside keeps it out of most black decks, but in the right shell that punishes opponents for it, the ceiling is real.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | not legal |
| pioneer | not legal |
| standard | not legal |
| vintage | legal |
| pauper | not legal |
| oathbreaker | legal |
Mold Demon is legal in Commander, Legacy, Vintage, and Oathbreaker, but its competitive ceiling is essentially zero in Legacy and Vintage — six mana for a 6/6 with a conditional life-loss trigger doesn't compete with what those formats are doing on turns one through three. Commander is the only format where Mold Demon has a plausible home: multiplayer means the life-loss trigger hits three opponents simultaneously, and a dedicated mono-black Swamp-heavy build can weaponize that immediately on entry. Outside of a Swamp-stacking deck, it still underperforms for the slot.

Budget Alternatives
Cheaper options that do most of the same work
If the life-loss trigger is the appeal, Ob Nixilis, the Fallen and Larceny apply consistent pressure without the self-damage condition and cost a fraction of the price. Mold Demon's trample body is real, but most black decks looking to drain opponents will find those alternatives do more work across more game states.
Price Context
Current price
$17.44 mid tier
At $17.44, Mold Demon sits in mid-tier pricing for a card with virtually no competitive demand — this is a collector price driven by age and scarcity, not play demand. It does not hold value the way staples do, and you're paying a significant premium over the card's actual in-game utility.
