I actually see some potential with this along with Muscle Band (also revealed: Each of the attacks of the Pokémon this card is attached to does 20 more damage to the Active Pokémon before applying Weakness and Resistance) and Virbank. That means that this would deal 170 damage along with the lock. I doubt that this will be that good though without the right support. As previous members have said the only thing it really has going for it is the 230 HP.
Also Tailow was also leaked and it has this ability: Once during your turn (before your attack), if this Pokémon is your Active Pokémon, you may have your opponent switch his or her Active Pokémon with 1 of his or her Benched Pokémon.
