And no, not even 1/3rd of the Steel types are viable. There are plenty that get shunted to lower tiers. Metagross is the 2nd weakest psuedo-legendary behind It That Shan't Be Named. Duraludon, Copperajah, Klinklang, Dugtrio-Alola, Aggron, Steelix, Escavalier, Wormadam, Perrserker, Mawile, Sandslash-Alola, Togedemaru, Stakataka, and Revavroom are all hot garbage.
A type's strength is not predicated on how good the Pokemon in the type are, either. If you made a type that's Super Effective against every type and resisted every type, but you only gave it to Sunkern, Tyrogue, and Magikarp, it'd still be an absurdly broken type even if 100% of the Pokemon with it are trash.
