The Pokemon trading card game is rather popular since fans and players get to Catch 'Em All. Like the majority of TCGs, Pokemon also has several expansions. "Sword and Shield" is one of the expansions in the Pokemon TCG.
This expansion focuses on the Galar region. This region also has some specific Pokemons that you can only find here. These are from the Pokemon V generation. One of the cards in this expansion is the Snorlax V. This expansion has a total of 200 cards, but one cannot know in advance what they'll find in a booster pack.
The booster packs in the Pokemon TCG feature only 10 cards. In any case, by getting these packs, you increase your chances of actually owning all the Pokemons.
