Nintendo: No, Decidueye is still a living pokémon, its ghost typing is from it harnessing spiritual energy!

Also Nintendo: "Harness the spiritual energy" of a Snorunt (ice-type) by poking it with a sun stone, and have a new ghost type which is literally the reanimated lifeless husk of an established species.
