A Showdown is marked as Staged at a Battlefield in the cleanup after the Contested status is applied to that Battlefield. 1. Showdowns that occur as a result of a player moving to an empty Battlefield are a stand-alone Phase and do not create a Combat. 1.a. These Showdowns are called Non-Combat Showdowns. During the proceedings of a Non-Combat Showdown, units controlled by a different player may become present at the Battlefield where the Showdown is ongoing. This will cause the Showdown to become a Combat Showdown in the following cleanup.
