link darkmoon cards of war back to the crafting recipe
assign the inscription spell darkmoon card of war an EV / profit.
the problem so far as i can tell is, that the individual darkmoon cards are not linked to the recipe.
this must be solvable as the enchanting spells offer the same problem being that the scroll is not directly made from the spell and i have found parts of the add-on files where this is dealt with, re-associating item IDs with spell IDs
as long as all the cards got linked to that recipe (like mass milling has multiple outcomes from one spell) you could adjust your prices like you would for any other crafting operation
thanks for listening to my rant if you have a solution please let me know
