This is The High Priestess from the Legacy of the Divine tarot, by Ciro Marchetti.
By far, this is one of my favourite Major arcana cards in any deck, and is often one of the cards I want to see before choosing a deck for myself.
This card represents sacred truth and hidden knowledge. She urges you to follow your intuition, and always remain receptive and aware. She also warns of secrets, and silent potential. Look deeper than usual...The truth and knowledge are there, but you have to open yourself to them.
Now, to pick a deck for this week! I may go to a three card daily reading, as opposed to single card.
