If Warwick attacks while Ahri Legend is defending, his attack trigger goes on the chain, then Ahri's trigger goes on the chain. After Ahri's trigger resolves (reducing Warwick to 4 Might), can a hidden Fox Fire be played to kill Warwick, and if so, does Warwick's attack trigger still resolve?

Question

Accepted Answer

Ruling: When Warwick is killed by Fox Fire after Ahri Legend's trigger resolves but before Warwick's attack trigger resolves, Warwick's trigger will attempt to resolve but the 'here' check will fail to find a location, so the damaged units will survive.

Sequence:
- Warwick moves onto the battlefield
- Attack/defend triggers go on the chain: Warwick's trigger first (turn player priority), then Ahri Legend's trigger second
- Ahri Legend's trigger resolves, reducing Warwick to 4 Might
- Hidden Fox Fire can be played as a reaction
- Fox Fire resolves, killing Warwick
- Warwick's attack trigger attempts to resolve but fails because Warwick is no longer 'here'
- Damaged units survive

Nuances:
- Fox Fire must be hidden at the battlefield beforehand to be played as a reaction, since it is an Action spell and cannot normally be played during combat
- Players can react between each ability resolving on the chain
