Next month’s CoroCoro Ichiban magazine will include a holo Flapple promo! Thanks goes to Toine L. for the translation!
[R] Flight Up: Attach up to 3 basic Energy from your discard pile to 1 of your Benched Pokemon.
[G][R] Acid Melt: 70 damage. Your opponent’s Active Pokemon is now Burned.
Unfortunately the magazine conceals the HP. Flapple from Sky Stream has 80 HP, so it’ll probably be around there.
