Yeah, the two main ones as of set 4 were Black Dragon and Death, but barely any cards actually suported those specifically. And now Deep is supported. DDW is a world where most interactions are through effects, rather than attribute.

FYI, only one card actually supports Asgard as an attribute (Navelbonds), so you can consider this world to be in a similar boat.
