The Art Gallery
Playable nowWhere you hang cards, and the second thing that supports people.
You can do this now.

Why you hang anything
A card hanging here supports people in your city, the same way served coffee does. Both add to your satisfaction, and they cost you completely different things.
Coffee- Costs resources every hour, forever.
- Cards in your gallery
- Costs nothing to keep, but a card on the wall is not in a deck.
What a card is worth depends on its rarity, and your Art Gallery lists what each one supports.
Hanging a card
Build an Art Gallery and open it. The wall has a frame for each level: press Hang under a card you own, and Take down to get it back. A card on the wall cannot be in a deck.
What the wall will ask for
Designed, not builtEach frame will ask for a different kind of card, and what they ask for will change every couple of days. Today a frame takes any card you own.
Anybody who scouts you will be able to see what is hanging there, so hanging your defending deck will show people how to beat you.
