Do changelings remain in changeling form when they get eternalized by the scarab god or one of the other two?
The changeling status is an ability on them, but I want to know for my commander decks in case I need to eternalize a changeling, and gatherer rulings didn't cover this interaction anywhere that I could see
MTG wiki gave me this
The rules that govern the interaction of continuous effects state that type-changing effects are applied before effects that add or remove abilities. This causes some unusual things to happen.
-If an effect causes a creature with changeling to lose all creature types, the creature won't lose changeling—but it will lose all its creature types.
-If an effect causes a creature with changeling to become a new creature type or types, the creature won't lose changeling—but it won't have all creature types anymore. It will be just the new creature type(s).
-If a card loses the changeling ability, it will still have all creature types. It just won't have changeling.
Relevant one is bold. My best guess is that this is a result of this
"Some static abilities are characteristic-defining abilities. A characteristic-defining ability conveys information about an object’s characteristics that would normally be found elsewhere on that object (such as in its mana cost, type line, or power/toughness box) or overrides information found elsewhere on that object."
Changeling overwrites the type line, which then gets overwritten by the not-Eternalize cards. The ability doesn't keep doing it so once it's overwritten it remains that way.
Ninjaed by a lot. O well.
