User comments:
First printing includes 44 cards with square-cut corners. It does not include any concentration indicator in spell duration entries, and also omits the card for the 5th-level destructive wave spell.
Version 2 includes 45 cards (adding destructive wave) with rounded corners and diamond-shaped "C" concentration indicators in spell duration entries.
Version 3 includes 69 cards (incorporating Paladin Oaths deck) in the same format as version 2.

Update (possible correction) on Version 3 (2017 copyright) - Total count is 70 cards (45 - Paladin Spells / 25 - Paladin Oaths)
