Offensively, I think it's not much of a stretch to call Poison and Steel the worst offensive types. I would also say Flying and Psychic, but with all the Fighting-types running around, your mileage might vary on that one. None of the above types hit more than 2 types super effectively, and even then, they're not exactly luxurious in coverage like Fighting, Ground, Ice, Fire, and Rock give. It doesn't help that they're all completely stopped dead by Steel.
Defensively, Ice is definitely the worst. Its weaknesses are all extremely common to the point of where I don't think there's been an Ice-type used in OU outside of Abomasnow, Mamoswine, and Kyurem, all of which have arguably been placed in lower tiers because
of their Ice typing.
So with that, I think it's clear of what we have to work with here. Poison, Steel, Flying, and Psychic
are the main candidates for offense; Ice
is the main candidate for defense.
