To the people below who don't get it, read the notes.

Pokemon booster packs come with 10 cards, including one rare (has a little star in the corner). This could be a Pokemon card (holographic if you're extra lucky) or a trainer card. I think most of us who were younger kids when the Pokemon craze hit only cared about collecting cool Pokemon, not playing the card game, so getting a trainer as your one rare card was really disappointing.
