"Tired of being solo on a Game Boy Advance using Ruby and Sapphire? Well, Nintendo has a solution! Introducing the "Pokémon Card e"! The Pokémon themselves are inside the cards! Using the new Card eReader+ for Game Boy Advance, and an existing Link Cable, connect one with the Card eReader+ to another Game Boy Advance and then slide the cards to battle with the other player! The Card eReader+' "Pokémon Card e" comes with some Pokémon and a sample bag of some items seen in the games. More "Pokémon Card e" cards sold separately. Rated E for Everyone by the ESRB."
