>>56636211>Cherrim Sunshine is swapped out from Cherrim Overcast when there is sun by the game's mechanics, not by the pokemon's abilities.except that hasn't been true for over a decade
>b-but that's gen 5 and this is a gen 4 game>>56636204>Whereas the innate ability of Arceus to change type with plates or more specifically anything with the legend plate is one of the pokemon's specific encoded abilitiesfrom Bulbapedia:
>Multitype changes the form and type of a Pokémon with this Ability depending on the Plate attached.>When a Pokémon transforms into Arceus, it becomes the same form and type as the target Arceus. If the transformed Pokémon is holding a Plate that is different from the target's held Plate, it then immediately changes to the form and type corresponding to that Plate; if it is not holding a Plate, it immediately changes to Normal Arceus (unless it transformed into Normal Arceus).it's important to note that this, unlike Flower Gift, was already dependent on Multitype in gen 4
