>>37096316Not that bad. Guaranteed crits mean you get to ignore SpDef buffs. There are better options but it's not a terrible move (and as
>>37096331said you could use it on something with Anger Point).
Anyways Synchronoise is worse since it only works against Pokémon of your own type, meaning it has a 17/18 chance of failing (16/18 if you're dual type) and it's also likely to be not very effective if you get STAB on it since Psychic resists Psychic.Even with its BP buffed to 120 you're still better off using, say, Confusion.
