In the early days of collectible card games players had to buy a
completely random set of cards and then try and cobble a playable deck
from the cards available. Then starter decks where introduced that
allowed players to play straight out of the box and then supplement
their deck by buying packs of randomised booster packs. It’s the format
that has worked for the world’s leading collectible card games such as
Magic: The Gathering, Pokémon and Yu-gi-oh. The system is stolen
wholesale from the trading card and or sticker album system and even has
levels of rarity with some of the most powerful cards also being the
rarest. This randomness means getting hold of the card you want requires
complete luck and could involve buying hundreds of booster packs.
