Can you play an Action card after another Action card has resolved during a showdown?

Ruling: Yes, after one chain resolves during a showdown, a player can start another chain with an Action or Reaction spell. Each player will have an opportunity to play Action cards during a showdown.

Sequence:

• Showdown begins
• Attacker has Priority and Focus, can start a chain with an Action or Reaction spell
• Priority passes to defender who can cast Reaction spells or pass
• When both players pass, the chain resolves
• Focus and Priority passes to the other player who can now start a new chain with an Action or Reaction spell
• This continues until both players pass Focus in a row, then combat damage resolves

Nuances:

• Both players need to pass Focus in a row to move to combat damage resolution
• The player with Focus can start a new chain with Action or Reaction spells after the previous chain resolves
