Type articles are fine. Welcome, even.
Just keep in mind that they are descriptive
classifications, not an inherent fact of biology. So the classifications are sometimes fuzzy, but generally convenient.
And prone to periodic revision. I like to think that, prior to ratification of a new classification system in the 90s
, Steel types were mostly placed in the Rock group, and Dark types were seen as a bizarre, dishonorable Fighting subclass. After the Dark and Steel classifications were introduced, Magnemite was added to the latter group, due to its unusual resistance to many attacks, but vulnerability to heat.
