Duelyst’s Unearthed Prophecy adds 94 total cards to the game. 16 neutral ones, and 13 cards per each class.
The expansion also features three new map tiles as well as a new keyword for the Songhai Empire, Abyssian Host and Vanar Kindred: Sentinel.
These cards lay dormant until the opponent does something to activate them, such as attack with their general or summon a minion. Then the sentinel pops up and lays waste.
There are also some nifty login rewards to receive some Orbs for the core set.
