japanese pokemon base set booster pack Pokémon: Abyss Eye (5 Cards) – Magic Chest Shadowy Secrets Base Set Booster Box Japanese

They can't be the target of spells or abilities, their static abilities have no effect on the game, their triggered abilities can't trigger, they can't attack or block, and so on

Ideally you should use a 10x loupe or better but thanks to the high resolution of the photos, we were able to crop in

Even within those three types, you can pick which pack to open from a random group

Essentially, you have a second hand and may use their cards instead of yours to leave them with no plays and potentially make them vulnerable to the table

I bought these sets easily
