Gold mine, Uncommon, 0 cost
Bricks prod x2
If #Quarry - #Enemy quarry > 1
Production x2


So if I take this onto my Unliving deck, once I get my Quarry to 5 (assuming the opponent doesn't add to his Quarry), I can play this for a free 15 bricks on top of the regular production? That sounds excellent, but the more I think about it, the less I think I would be willing to sacrifice an Uncommon spot for it.

The difficulty would be in wanting to save it until I've increased my Quarry. Playing it for a mere extra 3 or 4 bricks would be a terrible waste of an Uncommon, but keeping it on hand without the Unliving keyword would make it difficult to keep the token rotation going. I'd probably have to choose between saving it or a keywordless Rare to avoid gaining fewer than 50 tokens each Unliving play while hoping to draw the necessary cards to increase Quarry twice. In the end, as it stands now, I'd have to decline.

This could be great for facility increasing decks, not that I've seen one in a long while. I can't be the judge of that, though.

Well, it was planned like a card to support facilities increasement - right now Holy, Undead, Restoration, Nature and other stock+ cards are better, faster and stronger than facilities+.
But, I guess, I should soften this condition.

Much more tempting now. If this went live, I'd have to seriously consider it.

With a difference of only one facility, this could be useful for Destruction decks as well. (It wouldn't have before since the Destruction player would have been likely to reduce his own Facilities as well along the line, Kidnap notwithstanding.)
