I thought making the cards bigger too and now that you told me to do it too I'll do it
I also thought of writing the monster type somewhere on the card but a visual symbol is much more effective then a written text
With just a quick glimpse you can see whether it's melee or ranged instead of having to read it :D
And I also tried putting the symbol up in the top left corner but since the card's top is so darkened the symbol is harder to see....
So I guess I'll just make the card a little bigger and leave the symbol where it is
And as for the ranged symbol I'll either use a Target or 2 arrows in an X shape
I'll do it tomorrow and show you guys how it looks like
