Legend card, special card, rare card, common card.
Four types of cards, each assigned a score.
And until the closing time, the person who composed the deck with the highest score would be promised a prize.
There were some restrictions, though.
First, you couldn't include the same type of legend card in the deck. For cards other than legend cards, you could only include up to two of the same type. The score was calculated by pairing matching cards, with three of a kind counting as a pair. Lastly, the deck had to be composed of 30 cards or fewer.
Of course, to win, you needed to fill all 30 cards, and this was a quantity that was difficult to collect alone. Even those who bought high-value tickets had already spent a lot of coins, making it challenging.
People exchanged their drawn cards with each other or joined forces to create decks.
"Wait! I have one legend card and one special card. Please fit them into the deck."
