When using Agility in Team Play, can you specify which of the opposing team's Active Pokemon is affected by the Agility effect, or does it HAVE to be the Defending Pokemon that you are attacking with Agility?
It does have a you or your in it, so you would be able to select which opponent's active Pokemon it affects.

In Team Play, when an attack like Kakuna's "Secrete Poison" or "Agility" specifies the phrase "during your opponent's next turn", does that count for both opponents or do you have to choose one of the opponents to have the effect during their turn only?
You would have to specify which opponent.
