Base 70 attack a good pokemon does not make."oh, it's a Psychic type. It MUST suck."
That's probably why you never see it.
He can be tough to kill, so I'm surprised he's not used more...oh wait...people automatically think Psychic types suck.
For fuck's sake, this is effectively Castform's attack we're talking about here... Basically the problem is that deoxys can't hit back. Sure it can phaze and stall and whatever it wants but it simply has trouble doing damage.
In any case, by your logic, Reuniclus and Mewtwo and Mew must suck terribly.
