That's how every other Version-Exclusive Forme has worked (Skymin, Origin Giratina, SEP, Rotom). I saw a Battle Video with some Kami Pokemon caught in Dream Balls. So yeah.
Has anyone found Pikachu/Light Ball in anything? I know DW Pikachu was given out as an event, but I was hoping it would become more widely available. As well as Light Ball.
