Booster packs are typically packs of 10 cards from an expansion in the Pokémon Trading Card Game. Boosters offer the chance to acquire cards to strengthen Theme Decks, create new decks, or customize old ones. Boosters contain cards that vary by Rarity level, representing how likely or unlikely the card may be found in a booster. These Rarity levels include Common (), Uncommon (), and Rare () cards, as well as occasionally "super rare" cards such as Pokémon-ex, Pokémon Star, Shining Pokémon, Pokémon LV.X or Pokémon LEGEND.
- NOTE: For a fully description of Common (), Uncommon (), and Rare () cards see the Rarity article.
Booster packs have contained varying amounts of cards over the years. From the first Base Set through to Neo Destiny expansion, boosters contained 11 cards. Beginning with the e-Card Series and continuing through the entirety of the EX Series, boosters had only 9 cards. Since the release of the first Diamond & Pearl expansion, booster size was increased to 10.
Every Booster pack is guaranteed to contain at least 1 Rare () card, generally 3 Uncommon () cards, and the remainder are Common (). However, the Rare card(s) may have a rarity of Rare (★), Holofoil rare, or be a "super rare" card mentioned above, such as a Pokémon-ex. Since the release of the Legendary Collection expansion, one Reverse-Holo (also known as Reverse foil) print of a Common, Uncommon, or Rare card has also been included in every booster. A Reverse-Holo card is identical to its normal counterpart aside from a Holofoil effect in the picture or card background. Reverse-Holo cards in the EX Series also contain a stamp of the expansion logo in the bottom right corner of the picture. The inclusion of Reverse-Holo rare and Holofoil rare cards created the potential that one booster may contain two rare cards.
