There are 4 gold cards, one for each of the packs. A Pikachu, Charizard, Mewtwo, and Mew. You have a 0.013% chance to pull one of them. Congrats!

I love the stipple texturing!

I find stuff like that fascinating and often look sketchy stuff up unprompted. Weird hyper focuseses can take you down some interesting rabbit holes that seem really suspicious..
