Wyrdeer and Klevor are the same as Scizor, Togekiss, or any eeveelution past gen 1. They are a branch evolution from an existing pokemon. We havent seen one in 8-9 years and even then it was sylveon.Cards still state their regional forms, Galarian Mr Rime for example
It makes sense that they would make this move instead of making hisuian sneasles and ursarings since sinnoh is known for doing this in the og games with mons like yanmega, probopass, and roserade.
