Some months ago, I put online an application
called Geckos. Long story short, it's a website that works with templates, in the aim of producing cards for miniatures games (or anything else like RPG, board games, flyers, ...). Kinda like Magic Set Editor.

I just released the 0.3.1 version of Geckos, and with it I included a template for Frostgrave Monsters :

Hey, but I can make multiple styles for one template, so I put up one for Ghost Archipelago :

Yep, just another color and another symbol.
Feel free to use it, it's free (and open-source). You can do what you want with it, even modify the template. If you think something is broken, or missing, or could be made better, well, the
github project is there to get your thoughts.
Oh, you may want to test it on the demo page :
