Their abilities are set if they've more than one possible, but their natures are not and are affected by Synchronize. They also come with three random flawless IV's if you feel like soft-resetting. They're shiny-locked, though, if that matters at all to you. You also have to accept each of the Totem-sized Pokemon in order. (if you want Lurantis/Salazzle, you have to accept Gumshoos/Raticate and Marowak/Araquanid first)
