Electrode is receiving errata for the card to reflect that its Poké-Power can trigger when any attack Knocks Out Electrode, not just during its owner's turn. "If Electrode would be Knocked Out by damage from an attack, you may use this power. Electrode isn't discarded. Instead, attach it as an Energy card to 1 of your Pokémon. While attached, this card is a Special Energy card and provides every type of Energy but provides only 1 Energy at a time. (Has no effect other than providing Energy.)"
