The current plan for the deck includes two types of cards- predator/threat cards that will have an evocative illustration (of a fox, an NPC rabbit, a dense thicket, etc.) on the front. On the back of that card we'll put some descriptive elements to help the GM introduce it to the story.
Here's an example:
Quiet, lisping Peter Lorre voice
Spare a life in exchange for a later favor
Bask in the sun
Run from bigger things
The other type of card will be character moves, so that as players choose their moves from the central pool, they can take the card and put it in front of them. This isn't essential to play (you could just mark them on a sheet) but it should make things easier and it will look good on the table.
