The attack Magic Darts lists no damage number. The cost is Psychic, Colorless. Choose 1 of your opponent's Pokémon and flip 3 coins. This attack does 10 damage times the number of heads to that Pokémon. Don't apply Weakness and Resistance for this attack. Weakness is Psychic ×2. Retreat cost is 1.
I keep a set binder for Gym Challenge, meant to hold every card of that set. This card is one slot in the Gym Challenge set binder. A generation binder holds one card of each species. Mr. Mime can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Trainer's Pokémon, Kanto Gym Leaders and their Pokémon, and Sabrina and her Pokémon. I still need this card.
