Riftlands introduces two powerful and thematic asymmetrical powers for each monster-kin race. One is active at the start of the game and the other can be unlocked when you complete a Battle Plan. A new set-collection mechanic is added to Shadow Kingdoms through the 30 Relic cards you can acquire in the Riftlands, and each relic also has a unique power to further the player asymmetries. An additional 15 new Champion cards are also added to leverage the new mechanics and ideas presented in the Riftlands expansion.
