Promo, Parallel, Preview

Stargate had 31 promo cards. Three really dont count because one was a foil test card with small color blocks on it to test how the color came out in the foil. The other two were advertisement cards. One for the first set and one for the second set. So there really are 28 cards that fall under the Promo, Parallel and Preview portions.
