This is a simple card designer I made in the past two days for a game I'm working on. The monster art is not mine, and I do not claim rights to it. The illustration is clearly credited at the bottom of the starting card. The card artwork though, is mine. If you use this please credit me, but credit is not required. On the other hand, the cards are going to be copyrighted soon. I'm not stingy, so if you do go ahead and keep the same card appearance, I'm not going to make any problem for you. Just don't try to claim rights to the artwork.
This is a fully functional card designer. To use it, click on the object you'd like to change. If you don't check the box in the open image section on the gui, you can hold ctrl to reposition the image.
EDIT: Sorry about this everyone, I completely forgot that the background is solid black when saved rather than transparent, so here's the alpha for it. Just apply it as the alpha for the card in your favorite image editor (if it has that kind of tool) and it will set your card up for the game. I believe there's a way to do this in Construct 2 as well, but I forgot how to achieve those results.
