Each one of those cards has a code for a booster pack in pokemon trading card game live (PTCGL)

You don’t have to tell me your username or play with me but I’d appreciate it lol.

The game has no microtransactions, you can only earn packs and cards from playing or from codes from physical booster packs. It’s actually the same game as the physical cards, unlike pocket.
