op 02 booster box One Piece Paramount War OP-02 Japanese don’t miss out on cards from previous packs with Pirates Foil Bandai ONE Piece Card Game

I eventually found other Piplup collectors with their collections on Reddit and @citriina 's here on e4

These are divided between five different products: Scarlet and Violet Elite Trainer Boxes (you can find the Scarlet version for a reduced $49.30 at Amazon), booster packs, a Booster Bundle (available for $26.85 at Amazon, which is ever so slightly less than the MSRP), and a Mimikyu ex Box featuring the likes of Ghost-type Greavard

We often see collections like this come out in the next era as a way for The Pokemon Company to clear any leftover stock of the old expansions

By this point, a wider range of effect monsters, spell and trap cards had been introduced over the course of the previous six booster packs to offer a more expansive card pool, combined with the removal of rules restricting the use of spell and trap cards to just a single card per turn
