Pure Libram Paladin is getting one of the best cards in the Scholomance Academy by way of Devout Pupil.
You can quickly buff your cheaper minions and put Devout Pupil on board as early as turn three, and that's really strong for a 4/5 minion with Divine Shield and Taunt. Without doubt, the second copy will be played for free.
Since this is a dual-class card, it can also be played in the Priest class, but it currently lacks cheap buff spells, making its immediate use in the class null. For now, it's all about Paladin.
