They give more exp than a single card when used in upgrading.

I tested this with 2 Onmyoji. Without the use of arcanas, one fed with a level 1 normal went to level 2, while the other fed with a stone went to level 4 with 43 points until level 5.

When used with arcanas, a freshly dropped Rangda fed with a stone went to level 12 with 189 points until level 13.
