What happens if I use Cresselia's "Moonglow Reverse" attack to move a bunch of damage counters from my Pokemon to one of my opponent's Benched Pokemon while they have a Jirachi with the "Stellar Veil" Ability in play?
Moonglow Reverse would remove two damage counters from each of your Pokemon in play, but the opponent's Benched Pokemon would not receive any of them because it is protected by Stellar Veil.
