If I have Team Rocket's Ampharos with the "Darkest Impulse" Ability in play and my opponent's Team Rocket's Zubat with 40 damage evolves into Team Rocket's Golbat, do I get to use Team Rocket's Golbat's "Sneaky Bite" Ability before it gets KO'd?
Yes, you can. Since both Abilities are happening at the same time, the owner of Team Rocket's Golbat gets to choose the order they are applied.
