Does an initial chain get created if no units have 'When I attack' or 'When I defend' abilities?

Ruling: If there are no "When I attack" or "When I defend" abilities, there is no initial chain and combat goes straight into a showdown, giving the attacker focus to start a chain.

Sequence:

• Check for "When I attack" or "When I defend" abilities
• If none exist, skip initial chain
• Proceed directly to showdown
• Attacker receives focus to start a chain
