Decent approach too. Rather than memorize hundreds and hundreds of different species, easier to first learn common tells and traits. Make educated guesses from there if you ever come across something unfamiliar. Cannot always expect that you'll have studied it first.

[ identifying the potential typings of unfamiliar species on sight might become pretty relevant for the newcomers here, honestly, at least the ones without prior familiarity with Pokémon. ]

Hmmm. Don't suppose you want to be quizzed?
