I agree that even a harsh interp of Pokemon would likely be that only Normal type attacks are basic physicals, which is why dude is probably right. However. Still no PS4 here, but Random said in chat:
[02:22] <RandomKesaranPasaran> Since really for the evade boost to be worth anything at all against people that aren't like FE fighters you'd need to squint and go yeah sure this boosts the target's version of evasion
[02:23] <RandomKesaranPasaran> Since PS4 evade is actually kind of trashy for what it covers
If Saner's evade is actually not very relevant in-game, it might certainly be credible to say that no PKMN attacks count as PS4 basic physicals, and they all count as special moves. I'd certainly see any non-Struggle PKMN move breaking WA1o boss evade, for example. (It's only thanks to the DL I know that various WA1 bosses have 70% evasion or whatever, evasion that is totally worthless and invisible in-game since literally every single damage move you might seriously use in a boss fight ignores evasion.) But... not knowing PS4 well enough, I'm still personally defaulting to let Saner help here, unless some other people want to chip in about PS4 evade being super-narrow.
