The two pokemon kept dancing even as Boukun charged at them, but when his attack hit it would make an Illusion fade before the true Illusion herself appeared behind Bakeru and used Dark pulse at point blank range to destroy the disguise and then jump backward onto True Daenerys back as she went to use shadow claw on Mimikyu, it seemed Sashia plan was to take out the Mimikyu first since that held the biggest threat to her team. If both attacks hit then, Illusion would quickly make another Illusion to hide them, even if the attacks failed, Illusion would still ensure that the two of them would escape unscratched.
