I know you dont want to use models for this but...
you can try this:
entity Ace_of_spades
{
type = <space_ace.mdl>;
layer = 36;
view = camera;// Important
x = 50;
y = 10;
z = 10;
}
panels are much like entities. so within your code, you would simply use:
ace_of_spade_pan.layer = 36; /// FOR EXAMPLE
to bring it to the front, if there are cards behind it.

Not exactly sure what your trying to do, exactly; But I just wanted to try and help
