Bakeru's disguise was busted from the Dark Pulse, but the Mimikyu jumped off of Boukun, making Daenerys' attack hit Boukun instead.  "Boukun, Rock Slide; Bakeru, put a Curse on Illusion!"  Bakeru sensed Illusion and put a curse on the Zoroark at the cost of half of his HP.  Boukun roared and lots of boulders rained down all over the battlefield.
