When is a lane captured during combat - before or after the opponent gets to respond when focus is passed to them?

Ruling: A lane is captured after damage assignment, which occurs only after both players have passed priority consecutively without playing cards. Units must survive through all chains (including any chains the opponent initiates after receiving focus) before the lane is captured.

Sequence:

• Combat is initiated and chains resolve
• Both players must pass priority consecutively
• Damage assignment occurs
• Lane conquest/capture happens

Nuances:

• There is no limit to the number of chains that can occur
• If both players pass consecutively, showdown ends
• If the attacker (who has priority first) passes without playing anything and the opponent also passes, the attacker does not get another chance to play something
