Can multiple showdowns happen simultaneously when Ride the Wind causes a unit to move to another occupied battlefield?

Ruling: No, multiple showdowns cannot happen at once. They stage and resolve one at a time sequentially.

Sequence:

• First showdown stages and resolves
• Then the next showdown begins

Nuances:

• The person who applies contested (moves to the battlefield first) gets focus first
• If there is a defender present, the person applying contested is the attacker
• If there is no defender, you are not an attacker but still get focus first as the person applying contested
