I'm trying to see if I ran all the unique Pokemon in SWSH + DLC + Zarude what my total Pokemon would be in Pokemon Home.
Base Pokedex = 400
Armor = 211 (but there are overlaps with base pokedex)
Tundra = 210 (also overlaps with base pokedex and armor dex)
I've tried searching online to find the exact number of unique Pokemon in SWSH but it seems to roughly work out as one hundred new unique Pokemon in each DLC, so: 400 + 100 + 100 - but I'm sure that is not exact.
