After initial attack/defend triggers resolve, does the attacker retain focus?

Ruling: The attacker retains focus after the initial attack/defend trigger chain resolves. The attacker always gets to play an action first in showdown.

Sequence:

• Attacker has focus during the initial chain
• After initial chain resolves, attacker still has focus
• Attacker plays first action in showdown

Nuances:

• This is a known oversight in the rules that will be fixed in updated rules
• Focus is the ability to start a chain with activated abilities and spells; starting a chain with a triggered ability does not cause you to lose focus after that chain resolves
