I want to be able to easily list the forms I've added to a given Wagn. A Pointer of "all default cards" would let me do this with a Search with:

{"right": {"name": ["in", "*content", "*default"] },
   {"not": {"referred_to_by": "all default cards"} }
}

Rather than maintaining such a Pointer by hand (ugh) on English, a Search for all cards could be converted to a Pointer whenever new default cards are added. (This conversion would have to be done by hand for now, until we implement triggers).
