All transforming werewolves from sets before Midnight Hunt function as day/nightbound. Any newly nightbound werewolves that have effects that trigger upon transforming also trigger on etb to account for this change.
This is to make werewolves all function in the same way instead of having to track new and old werewolves separately without limiting the card pool to exclusively new werewolves.
