Well, we're not sure what set it's from, but their's a clefairy that copies an attack, here's what the attack reads "Choose 1 of the defending pokemon's attacks, Metronome copies that attack except for it's energy cost and anything else required in order to use the attack (such as discarding energy cards)"
so, scyther SF does 30 for 2 and cannot use that attack next turn, verdict? can clefairy use the attack twice in a row?
