The card text says: Flip a coin. If heads, search your deck for a Pokémon that has Team Aqua in its name, show it to your opponent, and put it into your hand. If tails, search your deck for a Basic Pokémon that has Team Aqua in its name, show it to your opponent and put it into your hand. Shuffle your deck afterward.
I keep a set binder for Team Magma vs Team Aqua, meant to hold every card of that set. This card is one slot in the Team Magma vs Team Aqua set binder. I still need this card.
