In a showdown, who gets priority first (attacker or defender), and can players respond to action cards with other action cards?

Ruling: The attacker gets priority first to react to triggers on the initial chain, then gets focus and priority first to play Actions/reactions. Actions cannot be used to react to anything - they can only be played when the chain is empty.

Sequence:

• Attacker gets priority first to react to triggers on the initial chain
• Attacker gets focus and priority first to play Actions/reactions
• Focus passes around during a showdown every time a chain is finished
• Defender can play Actions on an empty chain once they gain focus

Nuances:

• Actions require an empty chain to be played; they cannot react to other cards
