Is the Elementalist's Craft value what is printed on the card (1) or the combined total with his special rule (5) added for cards such as the warhorse?

You seem to know that the Craft Value is the value printed on the card.

The Elementalist gets +4 to his "Craft" if the elemental marker is flipped on the dark side. Not to his Craft value.

The Warhorse is not very good for him, but he actually doesn't need it.
