Challenge 0.8 is closed!
The winner is: @Thomadin
Congratulations! I found it quite interesting that all posted ideas developed in the same direction, so I think we got a nice foil card concept now.
But I fear we must wait for 0.9 to see it in the game. The 0.8 sprint will be a really, really heavy lift already, with a lot of bugfixes and balancing adjustments.
@Thomadin, your reward however shall make it to 0.8: Card of your choice, yeah!
