Each era, you and the enemy alternate taking turns, with you always going first. On the the enemy’s turn, the following happens:
1. The enemy plays the top card from its deck as the next card in its Leader Row.
2. The enemy resolves the card’s Leader Action (see Enemy Leader Actions).
3. After resolving the Leader Action, if it has the required Runes the enemy performs the card’s Rune Action (see Enemy: Rune Actions).
