The Celtic Oracle is a re-issue of the Celtic Shaman's Pack. It uses the same book text as before, but the cards don't use Chesca Potter's art, and instead have very different artwork created by a variety of artists.
The Templar Tarot is a unique art deck based on the legends of the Knights Templar, a medieval group of monks and warrior knights. It has 79 card, the extra is a major arcana card titled 'The Magic Flute'.
The second edition of the Templar Tarot has greatly expanded upon the first, both in number of cards as well the revelations and lessons in the deck. There are 22 new cards - 21 majors plus an extra 'Ascension' card - making a total of 101 cards in the deck.
