Nice work..!
This is EEVEE render, for rendering with Cycles you have to add background plane to card layer and mark transparency checkbox(render properties).
full scene made in blender, for rendering I use 2 layers to get this cool effect.
You can make changes and create your own cards.
For rendering full scene use Layer1.
converted: obj, fbx, stl.Separated objects in glb: card and pokemon(rigged)
