[W] Amnesia: 20
Choose 1 of your opponent’s Active Pokémon’s attacks. That Pokémon can’t use that attack during your opponent’s next turn.
[C][C][C] Swim: 90
If any of your opponent’s Pokémon have any [W] Energy attached to them, you may do 90 damage to 1 of your opponent’s Benched Pokémon instead of their Active Pokémon. (Don’t apply Weakness and Resistance for Benched Pokémon.)
Even fast-swimming fish Pokémon can be disabled by Golduck. It brings them to a standstill and seizes them.
