I can take this down once it's put on the site. I'd like to know three things.
Trying to remain as spoiler free as I can.
There are 242 Pokemon in total in the Pokedex (including Shaymin/Darkrai which require save data from SWSH/BDSP).
The dex consists of every Gen 4 Pokemon, plus a mix of Pokemon from other regions. See the full dex here (spoilers, obvs).
