TCG Card Shop Simulator – Card Rarity Probabilities Guide

Card Rarity Chances

• Full Art: 1 in 400 cards
• EX: 1 in 100 cards
• Gold: 1 in 25 cards
• Silver: 1 in 12.5 cards
• First Edition: 1 in 5 cards
• Any Foil: 1 in 20 cards

How Cards Are Generated

When you open a pack, the game creates 7 cards. For each card:

• The game picks a random number between 0 and 10000.
• It checks if this number is lower than the set chance for each rarity type.
• This check happens for each rarity type.

The first check is always for Foil (1 in 20 chance). Then it checks for other rarities, from Full Art to First Edition. If a check succeeds, no more checks happen. If no checks succeed, you get a Base Card.

Ghost Cards

Some packs can be Ghost Packs. In Tetramon packs, there’s a 1 in 1000 chance. In Destiny packs, it’s a 1 in 500 chance. In a Ghost Pack, the last card is always a Ghost Card. Ghost Cards have a 50% chance of a White or Black background. They still have a 1 in 20 chance to be foil.

I’ve opened 3,500 Tetramon Packs and haven’t received a Ghost Pack yet. My brother Jeremy has gotten 2 Ghost Packs in less than 1,000 packs. It seems like my luck isn’t very good in comparison.
