7 Wonders Duel: Pantheon - Rules of Play says:
The great Gods of ancient mythology get added to 7 Wonders: Duel in this new expansion, with each god having its own power to help you or hinder your opponent.
With Isis on your side, you can use a card from the discard pile to construct one of your Wonders for free. Zeus, whose nod determines what happens and what does not, enables you to discard any single card from the pyramid that you want as well as any mythology or offering tokens on it. The Phoenician goddess Tanit, whose people were renowned for trade, fills your coffers with twelve pieces of gold. Enki, the Sumerian god of crafts, technology, and creation, lets you choose one of two progress tokens. Minerva's ability to keep the conflict pawn from entering your territory may not instantly bring you victory, but it can save you from military defeat.The Pantheon expansion also includes two new Wonders: the Sanctuary and the Divine Theater
