When using Ride the Wind to move Yasuo into a battlefield during an opponent's turn after they moved a unit there, does Yasuo trigger his attacker ability and do you get a conquer point if you win?

Ruling: When you use Ride the Wind to move Yasuo into a battlefield that your opponent is attempting to capture on their turn, Yasuo is considered a "surprise defender" (not an attacker), but you still get a conquer point if you win the showdown because you did not control the battlefield at the start.

Sequence:

• Opponent moves their unit onto an uncontrolled battlefield on their turn, applying Contested status
• You play Ride the Wind as an action to move Yasuo into the same battlefield
• Opponent is designated as the attacker (they applied Contested status)
• Yasuo is designated as a defender (did not apply Contested status)
• If you win the showdown, you gain a conquer point because the battlefield was uncontrolled when the showdown began

Nuances:

• The attacker/defender designation is based on who applied Contested status to the battlefield, not whose turn it is
• Yasuo does not trigger his attacker ability in this scenario because he is a defender
• If you had controlled the battlefield at both the start and end of the showdown, you would not get a conquer point
