Mr. Reloaded
Cause a pirate is free
If it was meant to be a transfer only Pokémon then it wouldn’t have been listed as a static encounter this is further proven by the fact that a Keldeo and Victini are the only mythical Pokémon to be listed as static encounters in the dlc, while Volcanion and the other mythical Pokémon aren’t listed as static encounters and yet your able to transfer them in.
Having a static encounter in the code doesn't guarantee anything. Poipole and Cosmog also have static encounters but the way you receive those two are through gifts.
