When defending with a damaged unit on Reavers Row and Warwick attacks, can I retreat my unit using Reavers Row's ability before Warwick's attack resolves, since Warwick's focus ability goes on the chain first and Reavers Row resolves first?

Ruling: Yes, you can retreat your unit with Reavers Row before Warwick's attack resolves. Since Warwick's focus ability goes on the chain first, Reavers Row's ability goes on after and resolves first.

Sequence:

• Warwick's attack ability (with focus) goes on the chain first
• Reavers Row's ability goes on the chain second
• Reavers Row resolves first, retreating the unit
• Warwick's attack resolves, but the unit is no longer present

Nuances:

• The retreated unit will not be destroyed because it is no longer "here" when Warwick's attack resolves
