Can a defender lose control of a battlefield during a showdown (by moving their unit away with Fate of the Fallen), then move back with Ride the Wind before the showdown ends to score a point as a defender attempting to gain control?

Ruling: No, this specific sequence no longer works due to the updated rule that prevents control of a battlefield from changing while it remains Contested.

Nuances:

• You can still use Ride the Wind during your opponent's turn if they initiate another showdown to attempt to conquer the battlefield
