If the Defending Pokemon attacks Togepi during your opponent's next turn, any damage done to Togepi is reduced by 20 (before applying Weakness and Resistance). (Benching either Pokemon ends this effect.)
Flip a coin. If heads, choose 1 of the Defending Pokemon's attacks. Mini-Metronome copies that attack except for its Energy cost. (You must still do anything else in order to use that attack.) (No matter what type the Defending Pokemon is, Togepi's type is still Colorless.) Togepi performs that attack.
