How many Pokémon can be caught with a single copy of Platinum?

Question

Out of the 210 Pokémon in the native Platinum dex, how many are obtainable with only a single copy of Pokémon Platinum? This means no trading with Diamond/Pearl or from the Gen 3 games and no dual slotting.

Preferred if this was answered for the 493 national dex too.

Edit: Events that are no longer distributed also do not count, e.g. Arceus.

371, according to https://www.smogon.com/forums/threads/how-many-pokemon-are-obtainable-in-each-title.3690638/. Though I haven't gone through them all to make sure that's accurate :P

I think the only ones that are unobtainable are version exclusives, trade evolutions (besides Steelix, which can be caught), 2 of the starters, 1 of the fossils, Spiritomb, and Manaphy. This might also help:

Perhaps you should mention that this is a list of Pokemon you can't obtain?

i thought it said how many but it is nice to see a list but something tells me you are missing a lot of pokemon sumwun

---

also he said no event pokemon

Double-checked and the answer does include everything, the formatting is just pretty off to me. By event Pokémon, I'm assuming OP meant not to include them as obtainable, and this is a list of unobtainable Pokémon
