I know I can subscribe to individual cards once they're created. In addition, I want to be notified whenever a new card is created in the first place (so I can subscribe to it).
Alternately, if I could automatically subscribe to any new cards on a board, that would also solve the issue.

Subscribing to other entities, such as lists and boards, is covered in the Subscribe 2.0 card. It is in development as of this writing.
