Gacha

For the releases of the 4th and 5th sets of the TCG (BK4 & BK5), there were special smaller packs of trading cards you could get from Gacha vending machines in Japan. These smaller packs of 6 cards didn't have a guaranteed Rare like the normal 10 card pack however. There was also no visual difference between these cards and the cards you could find in the normal Booster Packs, unless they were Holofoil/Parallel. For the Holofoil/Parallel Rares and Super Rares, they have an alternate rainbow glitter foiling to them that is unique to the TCG, and only found in Gacha packs.
