It is a damn expensive rare. And while the cards they'll get will be entirely useless after the card effects, I think I'd still rather go with Golden Dragon (similar cost). Maybe cheapen card + reduce effect?

Even for the cost, its an extremly powerfull card, i mean, it completely shut down your opponents hand and his defensive abilitys. In a normal game, your opponent would sit there with 1 quarry and almost zero bricks AND the sort of cards with the highest brick costs and you can play whatever you want. Even for the high cost, this card gives almost directly any win you want and would cause frustration...

I have to agree with that. The biggest problem I have with this concept is that it eliminates fun for the opponent. I'd rather be on the receiving end of a devastating attack than have to sit there crippled and either wait for the situation to resolve itself or offer a surrender. This would be especially maddening in a game that goes only one turn a day.

Whatever suggestions we make, the game has to remain enjoyable as a primary tenet.

Damnation?

Damnation reduces facilities and stock very effectively, but with a single-resource cost it's easier to prepare against it, and if you're using expensive cards, it's possible that you have ways to increase the facilities you need. If you have 4 or 5 or your favored facility already, you're still in the game. If you're playing a 0-cost deck or cards cause or benefit from lowered facilities, you only have to contend with the attack elements.

The primary difference is that Damnation doesn't replace your hand, so if you didn't manage to discard it first, you're still able to carry on your strategy. It's the need to spend several turns discarding almost-guaranteed useless things that makes Curse of the still, as proposed, a frustrating chore.

Well, I's not so hard to exit the situation. And to restore your quarry back to 3 (If it was 3).

Restore everything after a damnation is much harder.

Totaly remade this into mass petrify. enemy can draw commons, while you cannot. Although lack of gems/recruits is a concern for both players.
