Excluding event-exclusive ones, I have all of them, with a 6IV Raikou, 6IV Kyogre and Shiny Tornadus standing out the most, as all others have either just one or no perfect IVs.
In what event-exclusive legendaries repects, I have a shiny RSE Mew, Wishing Ribbon Jirachi, Dusk Ball Deoxys with Psycho Boost, Darkrai, Shiny 6IV Darkrai, Shiny Shaymin and Shiny Genesect.
Which ones do you think would be fair for that Ninetales of yours? :3
