In a showdown, if the attacker passes priority and the defender plays a reaction (Shen), can the attacker play an action after the reaction resolves, or did they already pass their opportunity?

Question

Accepted Answer

Ruling: When a reaction resolves in a showdown, priority returns to the attacker. Damage only occurs after both players pass priority consecutively without playing anything.

Sequence:
- Attacker has priority first and may play actions or pass
- If attacker passes, defender gets priority
- If defender plays a reaction (like Shen), after it resolves priority returns to the attacker
- Priority alternates between attacker and defender until both pass consecutively
- Only when both players pass in a row without playing anything does damage occur

Nuances:
- A single pass does not lock a player out of future actions in that showdown
- Priority alternates back and forth (attacker, defender, attacker, defender) until both pass consecutively
