Wow great tool. I find it very inspiring, as I'm trying to build my own TCG and am looking for ways to do it.
But right now I'm still thinking about ways of how to create cards. I've ended up with developing a web-based tool for generating cards. Maybe this tool can be somehow integrated with your asset? I'm still a Unity-newbie, but I'm already tryint to recreate my logic in Unity.
It would be gratefull if you can take a look at my generator and provide any kind of feedback. I really respect your work and it would be very cool. Cheers!
