Synchronoise - A move that only works on Pokemon of the same type as the user? Who came up with that weird idea?
Quash - It makes the target go last, but it does no damage? Another weird idea. This move should've been turned into a damaging move, or cut from Gen 8.
Celebrate - Why waste a moveslot to make your Pokemon wish you a happy birthday?
Hold Hands - Another utter waste of a moveslot.
