I have a similar story. Simply put, my AI partner's Cresselia thought it would be a smart idea to spam Helping Hand after I died.I was playing Super Multis at the maison, my opponent were a Ninetales and a Gastrodon. I don't remember what I was using, but my partner was a Feraligatr with Waterfall, Aqua Jet, Earthquake and Ice Punch. The following turn my partner uses Aqua Jet on the Gastrodon, but doesn't work since it had Storm Drain. I KO the Gastrodon the next turn, and my partner uses Ice Punch on the Ninetales. Not so bad, he must have been aiming for Gastrodon, though the Ninetales KOs my pokemon and then the Feraligatr proceeds to spam Ice Punch three times on Ninetales... instead of his water moves of freaking Earthquake. Naturally Ninetales doesn't even feel it and gradually wears down and KOs Feraligatr costing me the run.
