In this regard, is Stonjourner a rare Pokémon?
Stonjourner is a rare find, but with a little luck and a lot of patience, players will be able to add the Big Rock Pokémon to their team before they take on the Elite Four. Unless found in a Max Raid Battle, Stonjourner won't appear until later in the game after the player has obtained the eighth badge.
Similarly, is Stonjourner a good Pokémon? Although Stonjourner carries nice stats on the physical side, an exploitable defensive typing as well as an atrocious special defense stat leave no reason to actually use this thing over other, more consistent, Stealth Rock setters, like Tyranitar and Excadrill, or maybe Ferrothorn if you're more of a defensive player.
Also to know is, what does Stonjourner evolve into?
It is not known to evolve into or from any other Pokémon.
