Lunumbra is an amazing artist that takes Pokémon Cards paint them.
Each piece is hand-painted with acrylic paint onto real trading cards . Details are added with gel pens or metallic ink and then two coats of a clear, protective gloss are added to give the card a shine and to help remove any unwanted texture. I take care to ensure every card is as flat as possible with few indications that paint has been added. If text is to be shown or if holographic details are wanted, a toothpick is used to slowly and carefully remove any unwanted acrylic.
Here is a video that shows him making a card:
