If a unit is moved out of a showdown (e.g., moving a Poro back), does the showdown immediately end, or is there still an action window for both players before it ends?

Ruling: Once a showdown has started, it does not immediately end when units are removed. Both players still have an action window, and the showdown only ends after both players pass priority in a row without playing anything.

Sequence:

• Showdown begins with valid units from both players
• A unit is moved out (e.g., Poro moved back)
• Both players still have their action windows
• Players can continue playing actions
• Showdown ends only after both players pass priority consecutively

Nuances:

• Having units from both players is not a requirement for showdown to proceed once it has started
• Nothing can stop the showdown from continuing once started, even if there are no units at all from both sides
