the move works fine in singles though does seem to be doing 1x the damage but that may just be me the issue i want to present is its automatic failure in double battles in the core games it targets who ever hit the user last and deals 1.5x the damage they dealt back but in here for doubles you first choose your target and regardless of whether or not you are hit that turn before you attack it fails my example being my doubles battle earlier today im using bastiodon which was much slower then the tyranitar that kept spamming dark pulse on it but 5/5 times when conditions were right metal burst failed
