This card sucks (for a rare). It should only affect your quarry (and it could be nerfed a little: +3 quarry).

I disagree. In a deck that uses bricks to great effect, it's an excellent card. Granting your opponent the same benefit is situationally a drawback, and from my experience it's well balanced at that.

Wonder is only useful in 2 types of decks: resource and unliving/tower building. Both of those decks are slow (especially compared to the current decks). This allows your opponent to go for the resource win (probably getting it since they don't plan for using large quantities of bricks) while they hit you with their normal stuff, forcing you to use your bricks. It's just very underpowered for a rare.

This card actually does seem a bit expensive to me. The rares that give an equal effect to both players (Order of the White Lotus, Return to the Beginning, New Era), often tend to be 0-cost. I don't think this card would be overpowered if it were too.

I agree, although it can give you a boost to victory. I don't think it's easy for the opponent to go to economic victory, before you can manage to build up your tower quickly. However a lower cost, or at least a lowering of rarity would be fit

The effect of the card is too great to 'just lower the rarity'.

It's not a bad card imo. Though I can get into the price argumentation (equal effect, so...).

I kind of liked the old picture better than the new one, which looks somewhat indistinct to me. I'm not sure what it's supposed to be... a colony of mold spores?
