Is a unit considered attacking when moving to an empty/uncontrolled battlefield, and what is the attacker/defender status when a unit is pushed into a battlefield via Ride the Wind?

Ruling: You are not considered attacking when moving to an uncontrolled battlefield. When a unit is pushed into a battlefield via Ride the Wind (or similar effects), the unit being pushed in is not the attacker; the player who originally applied contested status to the battlefield is the attacker.

Nuances:

• Wielder of Water would not get their +4 bonus when moving to an empty battlefield since no attack is occurring
• The attacker status is determined by who initiated the contested battlefield, not by who physically moved units there
