I'm just saying two things;
Silvally has a little bit of everything going on, is a friendship evolution, and can change types. And playing with the implications and little tic of type change has potential
And also Koraidon, a mon who's normally a sweetheart who's gentle enough that you can ride them has an established territorial/protective side where they stand up (becoming 9ft tall) and get ready to throw hands with most anything
Silvally is slept on for no reason, imo. Both by us pokefreaks and just, in general. Traumatized friendship evolution, Mewtwo-style copy of Arceus itself, false god beast killer? Evolves through friendship and trust? Hello? Let's talk about this thing more. It's one of the Pokemon of all time to me. Beautiful. And I can only imagine how the type change would play out.
Silvally changing types at will...suddenly turning Fairy when you're upset or angry to calm you with soothing energy from the colorful feather-things it's got going on. Fire type and its suddenly warmer, more energetic. Ice and its cool on a hot summer's day. Ground for stamina, electric for energy, psychic to read you, dark for mischief. It can be anything whenever it wants to be. Underrated.
Koraidon I'd say is also underrated, hehe. Sweetheart, gentle enough to ride, nine-foot-tall powerhouse lizard and king among the past Paradox Pokemon. Plus like, as of SV canon, they love people. Like, the Koraidon we saw? Super friendly and sweet. Big awesome lizard.
