About this card
Green hills and a bank of bright cloud behind the shoulder: Golem gets a real landscape, where nearly every holo ahead of it in the numbering floats on flat colour. It rears up with both clawed hands raised, a warm orange rim separating the grey plates from the hillside. Rock Slide skips the Active Pokémon entirely and drops ten damage on up to three of the opponent's benched Pokémon.
