The card text says: Put a Pokémon from your hand face down in front of you and tell your opponent the name of an attack it has. Your opponent guesses the name of that Pokémon, and then you reveal it. If your opponent guessed right, they draw 4 cards. If they guessed wrong, you draw 4 cards. Return the Pokémon to your hand. The card text says: You may play only 1 Supporter card during your turn (before your attack).
I keep a set binder for Unified Minds, meant to hold every card of that set. This card is one slot in the Unified Minds set binder. Themed lists that include this exact card are Kanto Gym Leaders and their Pokémon and Blaine and his Pokémon. I still need this card.
