In Showdown, does the turn player (attacker) play actions/reactions first, and can players continue playing actions after a chain resolves?

Ruling: The attacker gets focus/priority first in Showdown (usually the turn player but not always). Players can continue playing actions after a chain resolves until both players pass focus consecutively without playing anything.

Sequence:

• Attacker gets focus first and may play an action/reaction
• Defender may respond with a reaction
• Chain resolves
• After chain resolves, if both players have not passed consecutively, either player can start a new chain
• This continues until both players pass without playing anything
• Only then do units fight

Nuances:

• After each chain resolves, the player who did not have priority last can start a new chain with an action/reaction
• There can be multiple chains before units actually fight
• Units only fight after no player starts a new chain
