If the Defending Pokémon tries to attack during your opponent's next turn, your opponent flips a coin. If tails, that attack does nothing.

Weakness is Lightning ×2. The flavor text reads "Known to shoot down flying bugs with precision blasts of ink from the surface of the water."
I keep a set binder for Fossil, meant to hold every card of that set. This card is one slot in the Fossil set binder. A generation binder holds one card of each species. Horsea can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Mitsuhiro Arita cards. I still need this card.
