— In-game description
- Originally, this ability was called "Shuffle" and the card drawn had a chance to be the same as the previous one (so if you were to draw The Spire, the Astrologian may shuffle, and obtain another The Spire). This probability was eliminated in Patch 3.2, and the ability was renamed accordingly.
