Cartomancer

From publisher blurb:

Cartomancers are a special kind of spellcaster. They may look like wizards, bards or charlatans, but their magical abilities are unique: they can channel mystic powers through what seems to be an ordinary deck of playing cards. Every card they draw is a spell ready to use. As their casting style doesn’t allow them to prepare long-term strategies, they tend to be unpredictable and very good at improvising in difficult situations.

Their allies may find them a bit erratic at some moments and unhelpful at others, but the truth is that they are formidable spellcasters more often than not.
