Palworld is now Steam Deck Verified and SteamOS Compatible

Although you are correct (I think), with verified status you can actually open a ticket in case something does not work with proton. Usually the verified status is good for this use case. I do not know if games that are not verified can actually get support inside steam for proton (I doubt it).

Valve and Pocketpair are really making it comfortable for Nintendo fans to switch to pc gaming.

There are way better Pokémon-likes on Steam, like Cassette Beasts.

Tem Tem is way closer to being a proper Pokemon game and has been on Steam for years.

Didn't that remove Pal spheres because of the Pokemon lawsuit?

if it doesnt you should be able to map the button to aim the ball to also enable gyro
