A turn passes without anybody playing spells, so the Werewolf transforms. Is it still a Vampire? Or is it only the subtypes written on the card's new face?

# Yes.

From the [Comprehensive Rules](http://media.wizards.com/images/magic/tcg/resources/rules/MagicCompRules_21031101.pdf):

> 711.7. When a double-faced permanent transforms, it doesn't become a new object. Any effects that applied to that permanent will continue to apply to it after it transforms.

So your Werewolf will keep its Vampire subtype.
