Does a defending player get a conquer point if they successfully defend a battlefield they already control by swapping in a stronger unit during the showdown?

Ruling: No, the defending player does not get a conquer point. A player who begins the showdown with control of the battlefield and successfully defends it does not conquer because they already control it.

Sequence:

• Player begins showdown with control of the battlefield
• Control cannot be lost while the battlefield is Contested
• Contested status is removed at the end of showdown
• Player ends showdown present at a battlefield they already control
• No conquer occurs because control was never lost
