The Groundbreaker Theme Deck from the EX Legend Maker expansion of the Pokémon Trading Card Game predominantly focuses on and type Pokémon. Like other Theme Decks, Groundbreaker also includes a rulebook, damage counters, status counters, a custom coin, single-player mat and card list.
Rock your opponents when you play the Groundbreaker theme deck. First, rattle them with your Fighting and Grass Pokémon before you bring on Golem's Rock Tumble to win by a landslide!
