I'm thinking that Palosand and Wugtrio are cool as shinies.
Shiny Pokemon
Everything kind of depends.
Do you want something cool? Cute? A mix? Competitively strong? Casually strong? What type should it be? Which game do you want it in? How long are you willing to hunt? These questions need to be thought about before you get an answer.
All I will say is that S/S is way better than S/V at mesuda method, and keep in mind that in S/S you can go on dynamax adventures to get shiny legendary pokemon, however you can only hunt each legendary once. Legends Arceus is also great for shiny hunting, although you really don't know what you'll get.
Any thoughts on cool shiny Pokemon?
