The Phantom Cards (Japanese: まぼろしのカード Illusory Cards) are two cards from the Pokémon Trading Card Game and Pokémon Card GB2: Here Comes Team GR! for Game Boy. They can only be obtained through Card Pop!. Because a player can only Card Pop! with the same person once, these cards are considered the hardest cards to get in the game. There are two Phantom Cards: Venusaur (which can be obtained as an actual card with the purchase of the game's Player's Guide) and Mew. Both of these cards are needed for the Mysterious Pokémon Deck.
