If a unit is removed from a battlefield during a showdown, does priority continue and can players still cast actions even though no units are present?

Ruling: Yes, the showdown proceeds as normal until both players pass, even if no units are left at the battlefield. Players can still cast action cards during the showdown.

Sequence:

• Priority passes to the attacker to react to the removal effect
• Once both players pass priority, the chain resolves
• Focus shifts to the attacker (where they can play action cards)
• If both players pass focus, the showdown ends
