blue sky stream japanese booster box Pokemon TCG Sword & Shield (S7r) + Towering P – PokeWayne S7R-Blue Sky Stream Japanese Pokemon

Unlike regular expansions, where a player would receive a number of cards from a booster pack, these cards were only obtainable on randomized sheets from a Vending Machine from which the cards were peeled

When this card is Special Summoned: Target 1 monster your opponent controls

Up to four copies of each unique Pokemon card will transfer, so if you have four regular Pikachu cards, all those will transfer

Organized storage systems help maintain card condition and make collections easier to display, sort, and trade during events or tournaments

As such, the concept of an 'expansion' isn't really a thing, since there's no need to categorize cards for the purposes getting them out later
