For those who like the adversary cards, I created a fairly basic template in Scribus (free, open-source software) so you could do something without owning any Adobe products. It's still a little rough, I haven't tried printing, and only adversary cards are available, but someone might find it useful.

If you haven't used Scribus before, well, it's a bit of a learning curve. I plan on adding a tutorial a little later.

which version of scibus did you use?

my 1.4.6 (latest on ubuntu 18.04) wont work

I'm using 1.5.2 on Windows, so it seems you might be a little stuck.

since 1.5.x is unstable i will have to wait for 1.6 to be released.

but i am happy that you use open-source.
