Also I wouldn't say Castform is completely useless in single player. His special movepool is great and odds are that at least one of its moves are super-effective against your opponent.
I honestly can't think of a completely useless pokemon other than Ledian and Delibird.
Farfetchd, another notorious shitmon has access to sword dance and in-game npc are very susceptible to being set-up on. Shuckle, who is horrible to use in single player but it pretty useful on-line
