that attack is really funny because i just...never encountered it. Like I was showin a friend the fight and then saw it pull out this move and went "huh, never saw that"... Okay, so I've been stuck on what shouldn't be too hard a boss battle - I mean, I beat Centaurworld Palkia on the second attempt, and Arceus mostly has the same attacks - for fucking days, and it finally pissed me off enough to look up a video of the attack I've been having trouble with. That one where he uses Double Team, and it seems like you're supposed to stay in the circle while finding the real one, but the circle still instakills you and none of them are real.
As you might have guessed by now, yeah, it was bugged.
*stares at the camera*
Stocked up on a few health charms to tank the broken attack and rightfully kicked his cheating ass first try. ,,|,,
