Offering most of the legendaries that can be found in Shield, including a shiny Raikou I recently found on a dynamax adventure. Magearna is one of those mythical pokemon that's out of my reach in Shield without trading from the other games.
I can manage trades in either Pokemon Shield or Pokemon Home. Also willing to try and get you anything else you might want, but a legendary seems like the most fitting thing to offer. In any case, I will be awfully grateful!
