In a Riftbound showdown, if the attacker passes action priority to their opponent and the opponent plays an action, does the attacker get action priority back to play another action?

Ruling: Yes, when your opponent plays an action after you pass, you get action priority back and can play another action. The showdown only ends when both players pass in succession without playing anything.

Sequence:

• Attacker may play an action or pass priority
• If attacker passes and defender plays an action, priority returns to attacker
• If attacker plays an action and defender has no reactions, that action resolves before defender can play actions
• Showdown only closes when both players pass focus without playing a spell or activating an ability

Nuances:

• Both players must pass consecutively without starting the chain for the showdown to end and damage to be assigned
