I stumbled across a Warlock Class in the Card Suggestions which was done fairly well from an art & concept standpoint and I decided I'd enjoy messing around with the cards and see what I come up with.
The result is this complete Shadow Era add on.
World Beyond: Rise of the Warlock
20 new cards: 12 Warlock Class cards & 8 new shadow allies
