Since we're here, could someone explain why Psychic is super effective?
Narnia said (well, implied) so.
In (one of) the last book(s) in the series, someone gets sick and Prince Caspian's first response is to call for a psychic to heal her, implying that the psychic could somehow draw out the poison with its powers.
The type effectiveness has been changed before, "ya'll", and as it stands Poison is basically the worst offensive type besides maybe Normal - and Normal isn't really meant to be used for super-effective hits.
Ice needs the buff too, only defensively rather than offensively.
Only to fix some of the mistakes in first gen (like Psychic being immune to Ghost ) and to compensate for the existence of two new types...
Unless I'm forgetting something, there has been no changes made to the type effectiveness since second gen. Thus, there is very little chance of changes like Poison being strong against water being made now...
