When defending a battlefield, if a player uses Ride the Wind to move Yasuo to that battlefield during combat, does Yasou's 'When I attack' ability trigger?

Question

Accepted Answer

Ruling: Yasou's 'When I attack' ability does not trigger when moved to a battlefield where his controller is the defender. All units controlled by the defending player are considered defenders, regardless of when they arrive at the battlefield.

Sequence:
- Attacker attacks the battlefield and passes without playing Actions
- Defender plays Ride the Wind to move Yasou to the battlefield
- Ride the Wind chain resolves (Yasou's ability does not trigger)
- Focus passes back to the attacker, who can play Actions again

Nuances:
- After Ride the Wind fully resolves, the attacker regains the opportunity to play Actions and could use cards like Last Breath at that point
