When Volibear Furious attacks an enemy battlefield with Ahri, does his 'When I attack, deal 5 damage split among any number of enemy units here' ability kill Ahri before she can deal damage back, or does she get to deal her might back to Volibear?

Ruling: Ahri deals her damage to Volibear first, then Volibear's ability kills Ahri.

Sequence:

• When you attack, your "when attacking" abilities get added to the chain
• Then your opponent's "when defending" abilities get added to the chain
• The chain resolves backwards, so Ahri's ability resolves first (dealing -2 to Volibear)
• Then Volibear's ability resolves (killing Ahri)
