These are all the 140BP moves in the game, and of them 4 are current signature moves, one was a signature move in a past Gen and the final is a signature move, but unreleased officially (interesting to note, it can be called by Metronome, but unlike all other called moves, Smeargle won't be able to sketch it). This looks like it'll be another Signature move-type deal here, so most likely for the Box Legendaries movesets.
