I recently started going to a new league and there are players that that play the Mysterious Treasures Tropius. My question is, should the damage from Whirlwind be done before or after switching the active Pokemon. Here is the text on Whirlwind: :grass::colorless Whilrwind Your opponent switches the Defending Pokemon with 1 of his or her Benched Pokemon. I always thought that you do any effects of the attack be for doing damage is this correct? The people that play the Tropius's think that the damage is done before the switching. Thanks!
