To my noobish knowledge, the toolkit cards are visually 100% customizable without too much coding knowledge. There are 2 types of card visuals: one is a 2D widget and the other is the 3D card. You set these visuals in your card DataTable (EG BasicSet_DataTable for example). The Frame_texture, Image_Texture, and Back_Texture are for your 2D widget cards while Frame_Material, Image Material, and Back_Material are for your 3D Cards. The CCG Toolkit Documention mentions in the Technical Breakdown section that the “ViewCard” is “…a 2D visual container that can be easily be modified and filled with card specific data without needing to change or risk breaking gameplay related functionality.”
If you open the ViewCard widget (ViewCard_Default might be the precise name), you can change the size of the components to suit your liking. Your example card looks like the picture takes up the entire card space and is frameless. So if you redesign the frame backing to be transparent everywhere except the text blocks and resize the Card_Image to the full card, move/add the desired stats, you should get something close to, if not exactly, what you want. Whatever changes you made to the ViewCard widget, you can do for the 3DCard blueprint. Coding only needed if you add stats beyond cost, health, and attack. I have posted a quick mock up of what I described using the toolkit’s assets.
