No, it's not. In Black and White it was one of the harder to find Pokémon, but in later games they're more common to find in tall grass. Plus Pseudos tend to be dragon types with 3 stage evolutions lol
I can change it though if you'd like, it's no biggie ^^
I have a question. When you say HM/TM moves don't exist does that mean the physical disks from the game don't exist, or does it expand to an overall no Pokémon knows any HM/TM moves and they only know the basic leveling move set and egg moves?
