Clefable BS2 5

Metronome
Choose 1 of the Defending Pokémon's attacks. Metronome copies that attack except for its Energy costs and anything else required in order to use that attack, such as discarding Energy cards. (No matter what type the Defending Pokémon is, Clefable's type is still .)
Minimize
All damage done by attacks to Clefable during your opponent's next turn is reduce by 20 (after applying Weakness and Resistance).
Important Card Rulings & Erratas
- Metronome was mistranslated on both Clefairy and Clefable. While it does allow you to attack without the regular amount of Energy an attack requires, you must still do anything else required to use that attack, such as discarding Energy cards. The Japanese text emphasizes this, while in English, the translation was botched to clarify the exact opposite. This means that if Clefable used Metronome to copy an attack like Charizard’s Fire Spin, Clefable would still have to discard two Energy cards. If Clefable did not have two Energy cards attached to it to discard, the attack would have no effect. Future versions of Metronome-like attacks, like Togetic’s Super Metronome, included the proper translation.
