Confusing isn't it.
Probably a bad translation, that should say to any Defending Pokemon. Or says to any of your active pokemon.
Otherwise, this card will be called in every game. The real question is what is considered an Active Pokemon(that sounded n00bish)
Since your using the attack, it should be reffering to your active pokemon (saying any as a double battle clause)
But, as soon as it's your opponent's turn, your active pokemon is treated as the defending pokemon.
My guess. An double battle clause. If both you and your opponent have 2 active pokemon, and they get heads on confusion(induced by Pout) then they do +60 damage to either of your active pokemon)
Likewise, if they get tails, it does 90. But I highly doubt that. Far too broken
