This strategy is somewhat useful in case you have only 1 energy, a Gust of Wind, and a Clefable that's about to "kick the bucket". First, you need a Jungle Clefable (duh!). Second, you need an energy (any energy will do). Third, your opponent has to have a Ditto in play. Next, You put the energy on Clefable and gust out Ditto. Finally, use metronome on Ditto (which is now Clefable) and use it's minimize attack. Also, if you want to stall for a while, put 4 metal energies on Clefable so minimize can resist 60 damage (and 90 for psychic pokemon).
